```Error downloading Flow from S3: An error occurred (AccessDenied) when calling the GetObject operation: Access Denied```
I keep getting this error when flows are supposed to download their definitions from storage. I have both a prefect user and prefect role specified in the bucket's policy.

you would need to create S3 block with explicit access keys e.g.
```s3 = S3(
    bucket_path="prefect-orion/prod",
    aws_access_key_id="xxx",
    aws_secret_access_key="xxx",
)
s3.save("prod")```

in that case it'S most likely an issue of missing permissions on your execution layer
