@Marvin loading credentials for result_storage on a flow does not appear to work properly when loading an S3Bucket outside of a prefect flow or task.

It seems you are experiencing issues with loading credentials for S3Bucket blocks outside of a Prefect flow or task. Here are some key insights and potential solutions based on the documentation and reported issues: 1. Documentation Insight: The

S3Bucket

block should be used with

AWSCredentials

for authentication. Here's an example provided in the documentation:

from prefect_aws.credentials import AwsCredentials
   from prefect_aws.s3 import S3Bucket
   
   aws_credentials = AwsCredentials.load("my_aws_credentials")
   my_s3_bucket = S3Bucket(bucket_name="my_s3_bucket", credentials=aws_credentials)

Ensure you are using the

load

method correctly to fetch the credentials. More details: https://docs.prefect.io/latest/concepts/blocks/ 2. Reported Issues: - TypeError Issues: One common issue is with the

get_directory

method, which could throw a

TypeError

. A reported workaround is ensuring proper instantiation and saving/loading of the blocks. - AWS Client Parameters Stored as Dictionary: Another issue involves AWS client parameters being stored as a dictionary, leading to errors. Be cautious when assigning credentials through the UI and ensure the correct data types are maintained. Example:

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()
