AWS CLI version 2 returns strange hash

As per: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html

When you use a shared profile that specifies an AWS Identity and Access Management (IAM) role, the AWS CLI calls the AWS STS AssumeRole operation to retrieve temporary credentials.

These credentials are then stored (in ~/.aws/cli/cache).

You can try moving contents of ~/.aws/cli/cache/ to tmp/ and test command again.

Looks like this was some mess up with credentials. Not sure what aws cli was returning, hopefully not a secret key, but it starting working again once I managed to reset the default profile to use.

I also managed to print out the debug log when it was crashing:
