compress_state_machine functionality -- unable to download code package.

[alper-t]

I have a very long list of packages that I install via pypi, and I get the

"StatusReason": "Container Overrides length must be at most 8192"

I’m happy to see that this has been fixed in version 2.18.3, using the command:

Deployer(flow, environment="pypi").step_functions().create(max_workers=5, compress_state_machine=True)

But now I get the following error:

I replace the S3 bucketname with ***, but both bucketname and key are correct.
Does anyone know why this is happening?
