Step fails with no error message

[DuncanTormey]

I am using this action to run Django migration prior to deployment. It worked great the first time, but now the step is erroring out with an empty error message. I am not seeing the task show up in AWS console.

Here is the output I see:

Any ideas on what the empty Error might mean? At first I thought it might be a permissions issue, but the task worked great the first time.

Thanks for the great work on this GHA, really appreciate keeping this around when AWS should have implemented it 3 years ago.
