Can you share some code what are you trying to do and the error message?

10/21/2022, 10:24 PMI can reproduce it:
Copy code
from prefect.filesystems import S3
block = S3(bucket_path="my-bucket/example-dir")
block.save("example-block", overwrite=True)
block2 = S3.load("example-block")
block2.get_directory()Nico Neumann
10/21/2022, 10:30 PMI think S3 is using prefect + s3fs, not sure why it crashes.
prefect-aws offers S3Bucket which works for me:
Copy code
from prefect_aws.credentials import AwsCredentials
from prefect_aws.s3 import S3Bucket
aws_credentials = AwsCredentials(region="YOUR_REGION")
block = S3Bucket(bucket_name="my-bucket", basepath="example-dir", aws_credentials=aws_credentials)
block.save("example-block", overwrite=True)
block2 = S3Bucket.load("example-block")
block2.get_directory()🙏 3

10/22/2022, 12:07 AMok cool - it does work 🙂 It’s not expected behaviour though, right? I’ll raise the issue
