Why am I receiving 520 status codes from my app?
Your app may have crashed while trying to receive an upload or return a response larger than it has been configured to manage.
Why can't I access my environment variables at build time when building from a Dockerfile on App Platform?

If you are using a Dockerfile to deploy your app on App Platform, environment variables are only available at build time if you have set them using the --build-arg option in Docker before deploying the app.
For example, to access the variable EXAMPLE=your-value during build time, set it in the image using the docker CLI like this:
docker build --build-arg EXAMPLE=your-valueYou cannot use this method to access bindable variables at build time. If you are supplying a Dockerfile, bindable variables are only available at runtime.

Your team balance may be past due. Pay your balance to lift restrictions on actions you can take on the platform.
Why does my app not restart when it fails a health check?
If an app’s health check fails, the app currently does not restart. This is because App Platform does not currently support liveness probes. An app only automatically restarts if the app crashes or if its disk or RAM usage exceeds the its limits.
