Report #50726

[bug\_fix] An error occurred \(ExpiredToken\) when calling the GetCallerIdentity operation: The security token included in the request is expired

Run \`aws sso login --profile \` to refresh the SSO session. If using legacy SAML, re-authenticate via your identity provider.

Journey Context:
Developer starts their workday and attempts to run \`aws s3 ls\` using an AWS CLI profile configured for IAM Identity Center \(SSO\). The command fails with ExpiredToken. The developer checks \`~/.aws/sso/cache/\` and sees token files with yesterday's timestamp, realizing the SSO session has a finite lifetime \(typically 8-12 hours\). They attempt to use \`aws configure\` to reset keys, which fails because SSO profiles do not use long-term access keys. They search the error and find that SSO tokens are managed separately. They execute \`aws sso login --profile my-sso-profile\`, complete the browser authentication with their IdP, and subsequent CLI commands succeed.
