@Marvin using AwsCredentials.load outside of a prefect task or flow results in an error when using the credentials in S3Bucket Prefect.exceptions.ScriptError: Script at ... encountered an exception: 2 validation errors for S3Bucket credentials.MinIOCredentials Input should be a valid dictionary or instance of MinIOCredentials. Seems to think the input type is a coroutine and not a dictionary.

It seems the error you're encountering relates to incorrect usage of
AWSCredentials.load
with the
S3Bucket
block. Here’s a summary of what I found: 1. AWSCredentials and S3Bucket Setup: The correct usage involves loading the credentials within the
S3Bucket
block. The credentials should be correctly typed as an instance of
AWSCredentials
when passed. 2. Code Example from Documentation:
Copy code
python
   from prefect_aws import S3Bucket
   from prefect_aws.credentials import AWSCredentials
   
   # Initialize the credentials
   credentials = AWSCredentials.load("my_aws_credentials")
   
   # Use the credentials in S3Bucket
   my_s3_bucket = S3Bucket(
       bucket_name="my_s3_bucket",
       credentials=credentials
   )
Ensure
AWSCredentials.load
returns an appropriate instance of
AWSCredentials
. 3. Using Credentials Outside Tasks/Flows: To avoid coroutine-related issues, make sure
AWSCredentials.load
is awaited if it’s an asynchronous function. For more details, you can refer to the Prefect AWS Integration documentation. If the issue persists, consider checking the initialization and async handling of your credentials loading process.

@Marvin once I load AwsCredentials and S3Bucket, how do I set the result_storage on my flow for the entire flow to the s3 bucket I just loaded
m
Here’s how you can set
result_storage
for your flow using an S3 bucket: 1. Initialize AWSCredentials and S3Bucket:
Copy code
python
   from prefect_aws import S3Bucket
   from prefect_aws.credentials import AWSCredentials

   # Initialize the credentials
   credentials = AWSCredentials.load("my_aws_credentials")

   # Use the credentials in S3Bucket
   my_s3_bucket = S3Bucket(
       bucket_name="my_s3_bucket",
       credentials=credentials
   )
2. Set Result Storage: You can then set this
S3Bucket
as the result storage for your flow:
Copy code
python
   from prefect import flow
   
   # Define your flow
   @flow(result_storage=my_s3_bucket)
   def my_flow():
       # Your flow code here
       pass
   
   # Run the flow
   if __name__ == "__main__":
       my_flow()
For more specific examples and details, you can check the Prefect AWS S3 Integration documentation here: https://docs.prefect.io/latest/integrations/prefect-aws/s3/ Or, look at other flow examples here: https://raw.githubusercontent.com/zzstoatzz/prefect-code-examples/main/examples/flows/basic.py

this setup results in an error
@Marvin I am encountering the following error “TypeError: Result storage configuration must be persisted server-side. Please call
.save()
on your block before passing it in.
