👋 Hello, team! I am struggling to use an on-prem instance of MinIO as storage for my flows. My current design is: prefect server and minio server on a machine, prefect worker on another (beefy) machine whilst I do all my flow development on my laptop. Hence I'll deploy from my laptop to my minio storage for my worker to pick up the right job when needed. The problem I am encountering is that, when deploying I have:

botocore.exceptions.ClientError: An error occurred (InvalidAccessKeyId) when calling the PutObject operation: The AWS Access Key Id you provided does not exist in our records.

despite using the AWS Credential block with MinIO access.

Did you try MinIOCredentials block? https://prefecthq.github.io/prefect-aws/credentials/#prefect_aws.credentials.MinIOCredentials

Thanks @syakesaba I saw that and used it. However the problem seems to be when deploying. I am using “prefect deploy” which refers to a prefect.yml in there I think I should add the same credentials for the pull and push actions
