PERTAIN_TOProblem

it's being rendered server-side — component being loaded dynamically. Tension: I can't just tell it I don't want to use SSR for this project.

PERTAIN_TOSolution

so by wrapping components like — import dynamic from 'next/dynamic';. Tension: your child components will not use ssr. Outcome: remember to add 'use client' as well.

PERTAIN_TOProblem

the build fails and ends with the error: ' ELIFECYCLE Command failed with exit code 1.' — When I run pnpm run build. Tension: I deleted and reinstalled the node_modules, cleared the cache, and did everything, but the problem still persists. Outcome: Turns out y accidentally created a `filname.d.ts` file in my repository.

PERTAIN_TOSolution

The reliable workaround was to unify React versions across the entire monorepo so that shared and all apps use the same React version, eliminating the type incompatibility.

aws

PERTAIN_TOSolution

Run vercel build --prod --token=***. Tension: Error: spawn pnpm ENOENT. Outcome: Install Vercel CLI.

PERTAIN_TOProblem

FastAPI route works locally on / but fails on Vercel

PERTAIN_TOSolution

The most robust and recommended solution is to make your build script create the directory structure that Vercel expects. — Vercel Build Output API Structure. Tension: This gives you full control over the deployment.

PERTAIN_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_TOProblem

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.

PERTAIN_TOProblem

After the first request, all subsequent requests return the same timestamp — deploying to Vercel. Tension: even though I'm using new Date() in the handler. Outcome: The primary issue is with function instances being reused in Vercel's serverless environment.

PERTAIN_TOProblem

it uploads the file successfully, but just dumps the file on the "root" directory in Vercel blob storage — upload an image for example via the Payload admin upload feature. Tension: This makes my blob storage explorer in Vercel look very messy. Outcome: I would therefore very much like a folder for each project.

PERTAIN_TOSolution

your `getBrazilDateTime()` function correctly create a new Date object each time it's called — the serverless function's instance remains "warm" between requests. Tension: the outer scope of. Outcome: Objects declared outside of the function's handler method remain initialized.

PERTAIN_TOProblem

Type error: Cannot find module 'chrome-aws-lambda' or its corresponding type declarations. — Vercel raise:. Tension: import chromium from 'chrome-aws-lambda'. Outcome: Error: Command "yarn run build" exited with 1.

PERTAIN_TOSolution

Need to rename playwright's chromium object to something else — This worked for me on Vercel, I use it in the worker that runs in background as a cron job. Tension: args: chromium.args, executablePath: await chromium.executablePath(), headless: true. Outcome: await playwright.launch(.

PERTAIN_TOSolution

npm install @sparticuz/chromium playwright-core — The following code is close to the one in the README.md. Tension: This chromium package for serverless might help you. Outcome: This worked for me on Vercel.

PERTAIN_TOSolution

To alter this behavior, set a lower max-age on your static file. Tension: ensure the CDN is hit more frequently. Outcome: this might increase your hosting co.

PERTAIN_TOProblem

Cannot read properties of undefined (reading 'email') — in production, I get the following error. Tension: I need to send credentials (email, pwd, and id) via request headers in a GET request. Outcome: This works perfectly in my local environment, but in production.

PERTAIN_TOSolution

You are sending a `GET` request with `axios` so you can just remove the `req.body.xyz` parts — In the first instance I would just refactor your code. Tension: If you are not using a body-parser to parse incoming `POST` requests then `req.body` will not be accessible. Outcome: email = req.headers["email"] || req.headers?.email || null;.

PERTAIN_TOProblem

Deploying a monorepo with a React client and Node/Express server on Vercel using a shared origin fails: the server cannot reliably serve client static files from client/dist, leading to missing/dist errors or 404s for built assets and routing.

PERTAIN_TOProblem

vercel command is not found

PERTAIN_TOSolution

This is specific to Node installation. — Node installation. Tension: path environment variable for npm binaries is misconfigured. Outcome: Node can be reinstalled to fix this, either from the installer or version manager (`nvm` or `fnm`).

PERTAIN_TOSolution

If you have the vercel.json configuration file in your application, remove it. Tension: It is mostly likely the cause. Outcome: remove it.

PERTAIN_TOProblem

502 preflight error between Vue.js frontend and Express backend

PERTAIN_TOSolution

Use fetch instead of Axios

PERTAIN_TOSolution

Set origin to process.env.CLIENT_URL or http://localhost:3000 in corsOptions

PERTAIN_TOProblem

Cookie “__vercel_live_token” has been rejected because it is in a cross-site context and its “SameSite” is “Lax” or “Strict” — deployed it on Vercel. Tension: But i setup cookies in my project like this. Outcome: Then you need to use https://localhost:5000 and not http://localhost:5000.

PERTAIN_TOProblem

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.

PERTAIN_TOProblem

createPrivateKey() throws error:1E08010C:DECODER routines::unsupported on Vercel

PERTAIN_TOSolution

Convert the private key from base64, replace literal \n sequences with newlines, and trim before passing it to Octokit

PERTAIN_TOSolution

How to fix this issue — Next.js project deployed on Vercel. Tension: SQLite is incompatible with serverless environments. Outcome: Consider cloud databases like Postgres Neon, Turso, or Vercel Postgres.

PERTAIN_TOProblem

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

PERTAIN_TOProblem

Error: Failed to collect page data for /api/favourites/[drivingSchoolId]. Tension: the build process exits with code 1. Outcome: override Build command to `npx prisma generate && next build`.

PERTAIN_TOSolution

override Build command to `npx prisma generate && next build` — under Build & Development Settings. Tension: API route failed. Outcome: Redeploy the app.

PERTAIN_TOSolution

Use upload(`content/temp/${file.name}`, file, { handleUploadUrl, clientPayload }) and return the pathname settings from onBeforeGenerateToken()

PERTAIN_TOSolution

{"rewrites": [{ "source": "/(.*)", "destination": "/index.html" }]} — Do this in your vercel.json file. Tension: This might help. Outcome: Reference.

PERTAIN_TOSolution

Create a POST request to generate a signedUrl on the server — Send that URL to the client and POST the upload form with image to the S3 bucket. Tension: bypassing the server. Outcome: With that url you can POST directly to S3.

PERTAIN_TOSolution

"start": "node server.js". Tension: the build step but didn't run my server. Outcome: "dest": "server.js".

PERTAIN_TOProblem

No signatures found matching the expected signature for payload. — I tested with stripe-cli on local and it works fine. But after deploy to vercel. Tension: Are you passing the raw request body you received from Stripe? Outcome: The issue was not on Vercel.

PERTAIN_TOSolution

Stripe webhook endpoint provides two secret keys. — works in local development and (2) works when deployed to Vercel. Tension: One is provided in the sample code when setting up the new endpoint. Outcome: you can find in enpoint detail.

PERTAIN_TOSolution

Just deleted page.tsx — had both app/page.tsx and app/(page.tsx). Tension: which conflicted with each other since route groups `(public)` don't affect the URL path. Outcome: the Vercel build succeeded.

PERTAIN_TOSolution

check for useless page.js files in route groups — anyone else facing this error. Tension: This page does not do anything. Outcome: I found the problem.

PERTAIN_TOProblem

I'm unsure how to automatically obtain the preview app's URL for visiting it in Cypress tests. — How can I dynamically retrieve the URL of a preview app created on Vercel when a pull request is made in a Next.js project deployed via GitHub? Tension: I want to utilize Cypress for testing purposes on this deployed app. Outcome: can grab the URL of the preview from a github action event.

PERTAIN_TOSolution

you can grab the URL of the preview from a github action event — only runs this job on successful deploy. Tension: I'm unsure how to automatically obtain the preview app's URL. Outcome: setting it to the `CYPRESS_BASE_URL` environment variable.

PERTAIN_TOProblem

But my apis take long time sometimes. — I deployed Express.js to vercel. Tension: I'd like to increase server execution time limit but I'm not sure how can I do it. Outcome: I solved this issue by updating vercel.json.

PERTAIN_TOSolution

"functions": { "api/**/*.js": { "maxDuration": 60 } } — My entry point index.js file is in `/api` directory and other js files are in `/src` directory. Tension: I'd like to increase server execution time limit. Outcome: After I move other js files to another directory, it worked fine.

PERTAIN_TOSolution

python version could be defined in the `Pipfile`. Tension: python version could be specified in `builds` or `functions` section of `Vercel.json`. Outcome: Note Vercel only supports python 3.12 (default) and python 3.9 (requires legacy image i.e. use Node.js 16 or 18.).
