cluster-12

Deployment-time assumptions break on Vercel: serverless runs in a read-only app directory, install/build steps miss expected commands or env vars, and missing/incorrect dependencies or outdated .env values cause runtime and build failures.

INSTANCE_OFProblem

ReferenceError: require is not defined — on vercel. Tension: it work well in local. Outcome: if i comment this line and try to deploy this work properly but animation not work.

INSTANCE_OFProblem

`apps/serverless/tsconfig.json` is read by Vercel CLI because it crashes if I remove a curly bracket — The serverless app is part of a Turborepos monorepos (`apps/serverless`);. Tension: There is no root level `tsconfig.json`;. Outcome: I have tried different value permutations for the `exclude`/`include` fields.

INSTANCE_OFProblem

Prisma Client could not locate the Query Engine for runtime "rhel-openssl-3.0.x". — when I deploy. Tension: This is likely caused by a bundler that has not copied "libquery_engine-rhel-openssl-3.0.x.so.node" next to the resulting bundle. Outcome: Ensure that "libquery_engine-rhel-openssl-3.0.x.so.node" has been copied next to the bundle or in "generated/prisma".

INSTANCE_OFProblem

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.

INSTANCE_OFProblem

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.

INSTANCE_OFProblem

it seems to me that the `--prebuilt` tag prevents the whole source code to be shared/deployed to Vercel — deploy a FastAPI app using Github Actions to Vercel. Tension: apparently, Vercel can’t detect `.vercel/output/builds.json` file/folder ev. Outcome: without using the `--prebuilt` tag.

INSTANCE_OFProblem

INSTANCE_OFProblem

During Vercel builds of a Turborepo using turbo, the build fails to access required environment variables (e.g., DATABASE_URL) even though they are set in the Vercel dashboard. Locally, values from .env.local work, but CI/build cannot find them.

INSTANCE_OFProblem

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.

INSTANCE_OFProblem

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.

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.

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.
