Error in Setting Up Mainnet Follower Node

I attempted to set up the node using Docker Compose as per the documentation, but I encountered an error.

I provided valid AWS credentials as variables since my server is not running on AWS.
I don’t understand why the setup container is attempting to create an S3 bucket.
