Celery App Misconfiguration

celery-app-import-broker-misconfig

Celery starts and even reports a successful Redis connection, but the app instance is mis-specified (e.g., wrong module name / import context), so tasks don’t register or run; explicitly wiring broker settings fixes execution.

MATCHESSolution

`omnimart@0.1.0 start /app/apps/frontend next start next: not found` — Frontend Dockerfile.

MATCHESSolution

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

MATCHESSolution

I had to change the LOCAL git config — git config --global user.name "Your Name" git config --global user.email "your.email@example.com". Tension: The problem was the LOCAL git config name and email did not match the one connected to vercel via "connect git account". Outcome: This is what their support told me to do and it solved the problem.

MATCHESSolution

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(.

MATCHESSolution

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

MATCHESSolution

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.

MATCHESSolution

cleared next.config.mjs — Vercel.json was overriding proper build settings. Tension: Also, cleared next.config.mjs as I think some styling issues were occurring with SASS. Outcome: Working perfectly now!

MATCHESSolution

try replacing the following and try again — gem 'eventmachine', '1.2.7', git: 'https://github.com/eventmachine/eventmachine.git', tag: 'v1.2.7'. Tension: some days ago, it works great, but today it started to fail. Outcome: gem 'eventmachine'.

MATCHESSolution

I do have `credentials: include` in all of my requests — on vercel. Tension: the cookies were not persistent. Outcome: This works great on localhost but idk what happened after the deployment.

MATCHESSolution

Failed to launch the browser process! — The application works correctly on my local but not on vercel. Tension: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory. Outcome: I have been able to fix this issue by changing the Node.js version to 18.x.

MATCHESSolution

Always run Uvicorn from project root:. Tension: Add `--reload-dir` for extra folders (like your SQL hooks):. Outcome: python -m uvicorn main:app --reload --reload-dir path\to\hooks.

MATCHESSolution

There are a few things you can do. The first thing I would try is having a function which evaluates after import — the test setup will do the middleware patch. Tension: your function will return the correct value.

MATCHESSolution

Change the `mocked_app` and database `client` fixtures from `scope='session'` to `scope='function'` so each test gets a fresh app/client setup with a clean lifecycle.

MATCHESSolution

Outcome: CMD ["uv", "run", "retrofun.main:app_api", "--host", "0.0.0.0", "--port", "5555"].

MATCHESSolution

To manage background processes. Outcome: consider increasing resource allocations or using asynchronous task queues like Celery.

MATCHESSolution

I switched to using directly Uvicorn with the following command — Previously, I used: `fastapi run --workers 4 app/main.py`. Tension: the redirection then fails. Outcome: `uvicorn your_app:app --host 0.0.0.0 --port 8000 --proxy-headers --forwarded-allow-ips "*"`.

MATCHESSolution

I tried adding a `startup.sh` file with this command: `gunicorn -w 4 -k uvicorn.workers.UvicornWorker main:app`, without any luck. — Azure App Service. Tension: without any luck.

MATCHESSolution

you might need to add the path to the module like so — Dockerfile. Tension: Depending on where your Dockerfile is in your structure, which is unclear. Outcome: CMD ["uvicorn", "backend.app.main:app", "--host", "0.0.0.0", "--port", "8000"].

MATCHESSolution

env.py file. Tension: Alembic doesn't seem to recognize my models and creates empty migrations. Outcome: from dbModels import dbChat, dbImage, dbLike # ADDED target_metadata = Base.metadata # ADDED.

MATCHESSolution

Use python -m uvicorn with the correct module path in ENTRYPOINT

MATCHESSolution

adding Celery to your project — handling Stripe webhooks. Tension: This would allow for the processing of the webhook event payload to fail once (or more). Outcome: retry the operation.

MATCHESSolution

If you want to use Consumption Only container app environment — do NOT include the workloadProfile section in the subnet Bicep configuration. Tension: This means you don't need to add delegations.

MATCHESSolution

As a workaround, you may consider running `grype` as the `root` user — please test it on an image that wasn't previously pushed to the Docker Hub. Outcome: docker run --rm --name grype -u 0 -v /var/run/docker.sock:/var/run/docker.sock anchore/grype:latest --only-fixed mirekphd/ml-cache:20230731.

MATCHESSolution

Stage 2 (startup). Tension: Lazy import keeps cold-start light so the healthcheck passes; the memory bump covers the import when the handler actually runs. Outcome: functions-framework can bind the port.

MATCHESSolution

Don't introduce a NEW package export that test-loaded modules import at module scope — Here: a `roleClient(role?)` helper in the consumer package (`etl/llm-route.ts`). Tension: it forces you to update every `vi.mock` factory, and missing one re-breaks CI.

MATCHESSolution

redirect-uri: "https://localhost:41448/redirect-uri" — Here’s my application.yml configuration:.

MATCHESSolution

Adding it fixed my issue. Outcome: from .celery import app as celery_app.

MATCHESSolution

So after changing this line to the following, it worked for me. Outcome: app = Celery('projectSlackBot', broker=settings.BROKER_URL).

MATCHESSolution

Separate the Django web server and Celery worker into different containers or services

MATCHESSolution

Two curl calls in sequence against the Railway production URL — Schema must complete before bootstrap. Tension: bootstrap needs the constraints and vector indexes in place. Outcome: Apply schema first (synchronous — waits for completion).
