Celery App Misconfiguration

celery-broker-config-mismatch

Celery starts and appears to connect to Redis, but tasks fail to run because the Celery application instance is created with the wrong name/config (often from an incorrectly structured package), leaving broker settings unused.

MATCHESSolution

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

MATCHESSolution

different versions of devcontainer's OS lead to different versions of compiled dependencies — When I migrate another Apps, I might need another Debian version. Tension: this would lead to the packages land in the sam. Outcome: I figured out later.

MATCHESSolution

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

MATCHESSolution

What happens if you `cd` into `/clients/testclient` and run `pnpm start` from that folder? — Turbo starts the development server without issues. Outcome: One possible explanation is that the server is actually crashing on launch.

MATCHESSolution

Install `"turbo": "1.4.4-canary.0"` — with turobrepo > 1.2.6. Tension: without success. Outcome: solve the issue.

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

Configure Vercel to build the client with @vercel/static-build (output dist) and serve the client/dist from the Express server in production, using server-side express.static plus a catch-all route that returns client/dist/index.html. Add rewrites in vercel.json to route /api/* to the server entry and all other paths to /server/index.js.

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

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

I change config.yml and changed system.url-prefix: 'https:/IP' to system.url-prefix: 'https:/sentry.domain.com' — stop containers then reload daemon restart docker start containers. Tension: Origin checking failed - https://sentry-domain.com does not match any trusted origins. Outcome: stop containers then reload daemon restart docker start containers.

MATCHESSolution

Once you change your configuration, you'll need to restart all Sentry services — according to the docs. Outcome: by running docker-compose restart web worker cron sentry-cleanup (or just docker-compose restart to restart everything).

MATCHESSolution

Verify Sentry is initialized in the deployed process and that the DSN/config values are correctly applied; adjust Sentry initialization settings (e.g., disable PII with `send_default_pii=False` and/or enable `debug=True`) and ensure the server start command/environment matches what works locally (so events are emitted).

MATCHESSolution

Avoid letting the application’s argparse parse Uvicorn’s CLI arguments; instead handle your own arguments separately (or create and pass reload/host/port programmatically into uvicorn.run) so Uvicorn receives only its expected parameters.

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

Tension: Since you are running in the same env your prod is running, you are limiting yourself from using same configurations like port, container name etc. Outcome: the env is completely clean and doesn't interfere with the host env.

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

rename it and remove spaces, for example "Chat_101_APP" — The problem is because of the spaces in folder name "Chat 101 (APP)". Tension: Tailwind build failed error. Outcome: rename it and remove spaces, for example "Chat_101_APP".

MATCHESSolution

Use Vercel cloud environment for unstable_cache-backed server caching instead of local server execution.

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

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

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

Take a look at django-mailer — schedule it's management command through regular cron. Tension: It can replace the standard email backend and stores message queue in the db (so no Celery needed). Outcome: You just schedule it's management command through regular cron and that's basically it.
