Hi, I have an issue in prefect 2.7.7, when trying to deploy a flow using an S3Bucket block:

deployment build deployment_utils/maintenance.py:maintenance -n maintenance/maintenance -sb s3-bucket/<my_s3_bucket_block_name> -a

 f"Successfully uploaded {file_count} files to {deployment.location}",
    if not self.storage.basepath.endswith("/")
AttributeError: 'NoneType' object has no attribute 'endswith'

I tried also providing a basepath to the S3, and get a similar error.

AttributeError: 'PosixPath' object has no attribute 'endswith'

Files are uploaded to S3, but this error is raised. Anyone know what could be the issue?

Hi Tibs. I bumped into this issue over the weekend and have asked the engineering team about it. Will let you know what I find out.

Did you still have issues with this after upgrading to latest prefect-aws?
