there's a possibility that a token is invalidated between the time that it's created, so I wonder if checking cached is necessary at all

Checking cached ensures getRoleCredentials won't be stuck in an infinite recursion loop if some AWS bug was to cause CreateToken to return invalid or expired tokens. In these rare situations, I thought it would be safer to return an error immediately instead of possibly retrying forever.

Occasionally AWS returns 401 unauthorized errors on
GetRoleCredentialswith OIDC tokens that shouldn't have expired yet according to the expiration date returned by AWS. The error message in these situations looks like this:When this happened the only solution was to run
aws-vault clear.This error has occurred in the past when AWS returned the wrong expiration date for some time (#854 and #722) and it still happens occasionally to some users, I guess that's due to AWS invalidating tokens on some situations for security reasons.
This PR adds the ability for aws-vault to detect when a 401 error is returned, clear the cached OIDC token and retry the operation once with a new OIDC token.
