What could be the reason for a Python script failing with "Exit Code: 0" and "Unhealthy allocations" on Fly.io, and how can I troubleshoot it? I'm just trying a host a simple python script on fly.io.

week_number = now.isocalendar()[1]
print(f"Week number: {week_number}")

time.sleep(5)
if __name__ == '__main__':
periodic_task()

--> v4 failed - Failed due to unhealthy allocations - no stable job version to auto revert to and deploying as v5
--> Troubleshooting guide at https://fly.io/docs/getting-started/troubleshooting/
Error abort
- I tried procfile with
worker: python db_script.pyit didn't work. requirement.txtfile with and without codes of dependencies didn't work.- By increasing the time of
time.sleep()didn't work either.(tried for 5sec, 1hr) - I want to know what is the reason for this error and how to solve it.
Can someone please help me troubleshoot this issue and find a solution to get my task running on Fly.io? Any help is greatly appreciated. Thank you!
