botocore.exceptions.ClientError: An error occurred (403) when calling the HeadBucket operation: Forbidden

The above exception was the direct cause of the following exception:

sky.exceptions.StorageBucketGetError: Failed to access existing bucket 'skypilot-workdir-txia-60a9b7bc'. This is likely because it is a private bucket you do not have access to.
To fix: 
  1. If you are trying to create a new bucket: use a different name.
  2. If you are trying to connect to an existing bucket: make sure your cloud credentials have access to it. To debug, consider running `aws s3 ls skypilot-workdir-txia-60a9b7bc`.
