maybe missing dependencies in Railway Your requirements.txt or Pyproject.toml might not include all packages?

Here is what's helped:
Previously, the worker was started directly through the Procrastinate CLI command:
sh -c "sleep 5 && uv run procrastinate --app=app.tasks.app worker --queues=video_scraper --concurrency=2"
We changed the startup approach to run the worker through a dedicated Python file instead:
sh -c "sleep 5 && uv run python worker.py"
From a technical perspective, both approaches should start the same worker and perform the same job processing logic. However, the file-based startup resolves the Railway issue we were seeing with the direct CLI command.
We are still not fully sure why the direct command fails in Railway while the file-based approach works, but the important part is that the worker now starts correctly and the issue is resolved.
