This traceback usually results from package not installed in your container.

To get around, include this in your dockerfile:

RUN pip install prefect-aws

Or use EXTRA_PIP_PACKAGES

After installing the package, the error code is updated to:
botocore.exceptions.NoCredentialsError: Unable to locate credentials

I do have a MinIO Credentials block configured with root username and pass, and the S3-Bucket block references the MinIO Credentials block for credentials.
