Hi there looking for some help running an ECS Agent with S3 storage Getting a weird boto error

Sacha Ventura · Answer

```import prefect from prefect import task Flow from prefect storage import S3 task def print task logger = prefect context get logger <http logger info|logger info> f hello world with Flow hello flow as flow print task flow storage = S3 bucket= if name == main flow run ```

Sacha Ventura · Answer

I was able to get an ECS Service running the agent So I do have an agent running under the Agents tab in the Prefect Cloud UI

Sacha Ventura · Answer

I was able to get past `Error downloading Flow from S3 Unable to locate credentials` by providing all the possible combinations of AWS env vars in the task definition container

Now I m getting something that looks like a boto error ```15 58 12 INFO agent Submitted for execution Task 15 58 47 INFO S3 Downloading flow from s3 hello flow 2022 03 29t04 10 25 834594 00 00 15 58 47 ERROR S3 Error downloading Flow from S3 str object has no attribute get 15 58 48 ERROR execute flow run Failed to load and execute flow run AttributeError str object has no attribute get ```

The AttributeError you get comes from boto3 not Prefect you need to create a task role IAM role with S3 permissions ECS won t work with credentials provided as env variables
