v3 failed - Failed due to unhealthy allocations - no stable job version to auto revert to and deploying as v4

I’m trying to deploy a simple flask program. I don’t know what the error is and how to debug it?

Can you share your fly.toml file?

With the logs that you’ve shared I can see there is a ModuleNotFoundError: No module name ‘server’. Fix it and see if you can deploy it.
