lakeview requires specifying a region

Encountered by a community memeber on Slack. Running the lakeview docker run command results in the following error:

botocore.exceptions.NoRegionError: You must specify a region.

Either add code to discover the region of the bucket, or document (in the README and blog post) how to overcome this (for example, by adding the AWS_DEFAULT_REGION environment variable to the command).

try passing the region as an environment variable with -e AWS_DEFAULT_REGION="us-east-1".

had this same problem and then was stopped in the lakeview web page with "Unable to locate credentials".

possible that both errors are the result of lack of support in lakeview for SSO access tokens? lakeview container has access to ~/.aws but can't seem to find the credentials.
