Utilizing Boto3 to connect to verify if any s3 buckets that consist any ACL or Bucket policy

Question

I have a python script that is working half way, it errors-out at for bucket in conn.buckets.all() .

Here is what I have got so far:

The error is:

An error occurred (AccessDenied) when calling the ListBuckets operation: Access Denied: ClientError ClientError: An error occurred (AccessDenied) when calling the ListBuckets operation: Access Denied

I have given full access to the user and the policy that is attached to the role that is being used by the Lambda function.

Answer 1

conn.buckets.all() returns a list of buckets already; the next two lines after the for loop should be removed.

Answer 2

Thank you for your help everyone, it was just the permission issue with the role that was utilized by the lambda function. LIST permission were not specified.
