RELATES_TOProblem

Error occurred prerendering page "/post/1" — I'm trying to deploy a blog written with Next.js v15.3.3 with Vercel. Tension: TypeError: Cannot read properties of null (reading 'useState'). Outcome: Export encountered an error on /post/[slug]/page: /post/1, exiting the build.

PERTAIN_TORootCause

it just breaks everything — when I hit 404 error. Tension: prefetch would just skip. Outcome: the prefetch would just skip.

ESCALATES_TOProblem

Got HTTP 400 with "missing mcp-session-id" on every call. Tension: The MCP StreamableHTTP transport is not stateless — it requires an explicit session handshake before any tool call. Outcome: Implement the full session lifecycle in the client.

MANIFESTS_ASProblem

the image is not loading — whenever the email is delivered to an inbox. Tension: the `src` of the image goes to a `404` page. Outcome: To serve the images better you should look at a service like Vercel blob.

MANIFESTS_ASProblem

CssSyntaxError: tailwindcss: C:\Users\aayus\Projects\e-commerce-platform\packages\ui\src\styles.css:1:1: The border-border class does not exist. — windcss -i ./src/styles.css -o ./dist/index.css. Tension: If border-border is a custom class, make sure it is defined within a @layer directive. Outcome: Rebuilding...

MANIFESTS_ASProblem

the whole app breaks and throws errors in console — when I hit 404 error if, for example, I manually change the url to a wrong one. Tension: I intuitively thought that in case of problems the prefetch would just skip.

MANIFESTS_ASProblem

after deletion it invalidates both list of users and single user that couses unnesesary 404. Outcome: That's not going to work.

MANIFESTS_ASProblem

if I go directly https://jbetoreyes.github.io/beyond-brand-boosters/about-us I get a 404 — I'm using react + tanstack router + github pages. Tension: page loads fine, but if I go directly. Outcome: use hash-based routing which is documented here.

MANIFESTS_ASProblem

GitHub Actions cannot resolve actions/actions-gh-pages and the deploy step stops

MANIFESTS_ASProblem

FastAPI route works locally on / but fails on Vercel

MANIFESTS_ASProblem

Error occurred prerendering page "/post/1" — I'm trying to deploy a blog written with Next.js v15.3.3 with Vercel. Tension: TypeError: Cannot read properties of null (reading 'useState'). Outcome: Export encountered an error on /post/[slug]/page: /post/1, exiting the build.

MANIFESTS_ASProblem

GET https://cooking-assistant-phi.vercel.app/static/css/style.css net::ERR_ABORTED 404 (Not Found) — I'm deploying a Flask app to Vercel. Tension: Locally it works perfectly — static files like CSS load and the page looks as expected.

MANIFESTS_ASProblem

Tension: the backend doesn’t seem to be serving requests, and the frontend likely fails due to a dependent API call. Outcome: The deployment succeeds (`READY` state).

MANIFESTS_ASProblem

Error: Can't deploy more than one path. Tension: I already tried to delete the vercel.json file as there are two cron jobs defined which according to the vercel AI assistant could possibly cause the issue. Outcome: Verion of Vercel CLI: 37.14.0.

MANIFESTS_ASProblem

works perfectly in local development — when I try to make it production-ready on Vercel. Tension: I encounter issues.

MANIFESTS_ASProblem

No response is returned from route handler — app/api/test/route.ts. Tension: Ensure you return a `Response` or a `NextResponse` in all branches of your handler. Outcome: We can fix this by giving a default response like this:.

MANIFESTS_ASProblem

When accessing a bad url supposed to be 404 have this error `This Serverless Function has crashed.` — Angular SSR deployed on Vercel Serveless Function. Tension: my angular app routing could never do the job of redirecting to the correct /404 or just display the 404 component.

MANIFESTS_ASProblem

Angular SSR deployed on Vercel Serveless Function. Outcome: It also works doing `node dist/project/server/server.mjs` (after a build using server.ts).

MANIFESTS_ASProblem

I have a route `/property/:id` that includes a button which, when clicked, should redirect to `/profile/:id`. Tension: It only seems to fail when trying to redirect from `/property/:id` to `/profile/:id`. Outcome: in console it shows response 404.

MANIFESTS_ASProblem

whenever I send the link to someone else, it says they have to login on Vercel to view the portfolio — deploying it to Vercel. Tension: I've tried checking the settings for any public or private restrictions but either I can't find it or it's not there at all. Outcome: Go to your project settings, here in Deployment protection you can find vercel Authentication setting, turn it off, now you are good to go.

MANIFESTS_ASProblem

Refused to load the script 'https://conoret.com/dsp?h=car-doctor-server-bay-rho.vercel.app&r=0.47386382518756887' because it violates the following Content Security Policy directive: "default-src 'none'" — I deployed my serversite code in vercel, but my site replied with status code 404. Tension: Note that 'script-src-elem' was not explicitly set, so 'default-src' is used.

MANIFESTS_ASProblem

Sometimes it works, sometimes it does not catch the issue, just runs over the error. — I use pdb to debug in Django. Tension: Django server just gives a "non_field_errors":["Something unexpected has occured. Please contact an admin to fix this issue."]. Outcome: Sentry can show the hot spot.

MANIFESTS_ASProblem

User information was not being attached to all Sentry events globally in a Next.js app. Attempts to set `Sentry.setUser` in the Next.js error component (`_error.js`/`getInitialProps`) did not result in user data being included.

MANIFESTS_ASProblem

<sys>:0: RuntimeWarning: coroutine 'Connection._cancel' was never awaited — Pytest in FastAPI + Postgres. Outcome: To fix this one method is to dispose the engine after every test route.

MANIFESTS_ASProblem

response = client.put("/v2/shield?a=false"). Tension: assert response.status_code == 200.

MANIFESTS_ASProblem

If I use `https://my.url.de/qgis/static/index.html` I get an Error 404. — I want to use a static HTML page in my docker to show logfiles via websockets and FastAPI inside a docker container.

MANIFESTS_ASProblem

When deployed on Azure App Service behind a proxy, FastAPI/Starlette redirects requests to an HTTP URL (e.g., HTTP Location header in a 307) instead of preserving HTTPS. This causes browser mixed-content/security failures because the app is loaded over HTTPS but redirected to HTTP.

MANIFESTS_ASProblem

it says `404 not found` — I succesfully deployed my FastAPI app to azure, but when I try to access the routes. Tension: However, when I tested the same routes locally, they worked. Outcome: I've successfully deployed your code to Azure Web App and have been able to access the routes.

MANIFESTS_ASProblem

using FastAPI. Outcome: If I do: `@app.post("/instance/new", tags=["instance"], PlainTextResponse)` I get an error when returning a JSON response.

MANIFESTS_ASProblem

a CancelledException is created and the frontend recieves "internal server error" — when I raise it with with `raise HTTPException(status_code=404, detail="Item not found")`. Tension: I want to be able to return an http exception like "404 Not found" to the frontend. Outcome: How can I pull this off?

MANIFESTS_ASProblem

This fails to determine available image versions. Tension: Dependabot cannot access variables in its GitHub Actions jobs, only secrets.

MANIFESTS_ASProblem

there's no `index.html` here hence the 404 Page not found error — the GitHub Pages deployment is from `docs/html`. Outcome: Changing `OUTPUT_DIRECTORY` to `./docs` on line 9 and removing/commenting line 38 should resolve this issue.

MANIFESTS_ASProblem

In GitHub Actions, the same workflow job cannot automatically use environment-specific context (e.g., vars) across multiple target environments. `vars.CLUSTER_URL` is not resolving unless the job specifies an `environment`.

MANIFESTS_ASProblem

Client error with status 404 Not Found — I'm struggling to read data from S3 via polars. Tension: The data is layed out in S3 with what I believe to be Hive Partitioning.

MANIFESTS_ASProblem

it still returns 200 OK — when the object doesn't exist. Tension: where I expect a 404 Not Found error. Outcome: How do I modify my CloudFormation template so that a request for an unknown S3 key results in an HTTP 404 response?

MANIFESTS_ASSolution

You need a method response for the 404 status code. Tension: This way, you return a 404 response from your API Gateway for a 404 error from S3.

MANIFESTS_ASProblem

The app throws ApiNotActivatedMapError when using @react-google-maps/api StandaloneSearchBox for Google Places autocomplete, even though the API key appears to work for Maps/Places requests.

MANIFESTS_ASProblem

I have an endpoint that throws 404 when nothing is found. — in my app. Tension: I want to treat those 404 of that endpoint as a 200. Outcome: potentially return an empty array.

MANIFESTS_ASProblem

jakarta.ws.rs.NotFoundException: HTTP 404 Not Found — every time I try to create a user or view the realm representation. Tension: I keep encountering a jakarta.ws.rs.NotFoundException. Outcome: Any help on why this could be happening?

MANIFESTS_ASProblem

The production API returned 404 for the expected admin cleanup route — A demo benchmark needed to wipe only its own graph namespace before each run. Tension: the harness could not authenticate cleanup because the local secret used an older environment variable alias. The fallback was a manual Cypher delete, which made clean runs unreliable.

MANIFESTS_ASProblem

graph cleanup, MCP config, and hooks defaulted to production inErrata URLs — A CTF demo benchmark was intended to run entirely against a local compose stack. Tension: The local compose API also failed after rebuild because production-mode startup required a Turnstile secret, and its healthcheck used wget even though the Node slim image did not include wget. Outcome: The local compose API also failed after rebuild because production-mode startup required a Turnstile secret.

MANIFESTS_ASProblem

delete fails with 404, meaning it can't find the endpoint — My react app successfully gets and posts from/to Spring Boot JPA MySQL db. Tension: delete fails with 404. Outcome: meaning it can't find the endpoint.

MANIFESTS_ASProblem

The Next.js app fails to render the Supabase-backed UI and returns an HTTP 404 error while trying to fetch data from a Supabase table.

MANIFESTS_ASProblem

The Docker Hub website returns a 404. — I have tried using the following images: `openjdk:21`, `openjdk:21-jdk` and `openjdk:21-oracle`. Tension: Apparently the OpenJDK distribution for Java 21 is missing from Docker Hub.

MANIFESTS_ASProblem

When using jOOQ to translate a JPA-style REST DELETE/UPDATE flow, the user needs to detect whether the target row exists (and/or is accessible) by relying on the number of affected rows. The approach should map 0 deleted rows to HTTP 404, 1 to success, and >1 to an invariant violation.

MANIFESTS_ASProblem

{"type":"about:blank","title":"Not Found","status":404,"detail":"No static resource gggg.","instance":"/gggg"} — I have a spring boot application with an angular frontend. I migrated it from spring boot 2.7.18 to 3.3.11. Tension: This seems not to work anymore after migration. No redirection. Outcome: redirect all not found pages to root.

MANIFESTS_ASProblem

it throws me an odd error: — spring.ai.openai.model=gpt-3.5-turbo. Tension: Why is it automatically assumed I need gpt4o? There are no references of gpt4o anywhere in the code.

MANIFESTS_ASProblem

LSP diagnostics silently never reconciled on Windows — Converting an LSP / VS Code file:// URI to a filesystem path. Tension: the diagnostic just never matched a file.

MANIFESTS_ASProblem

Outcome: However I found a way around this issue.

MANIFESTS_ASProblem

I get a Page not found error 404. Tension: The current path, detail/PayPal, matched the last one.
