Report #84462

[bug\_fix] The provided token has expired or is invalid \(UnauthorizedException from SSOOIDC service\)

When using AWS IAM Identity Center \(successor to AWS SSO\) with the AWS CLI v2 or SDKs configured for SSO profiles, the authentication flow caches an SSO access token \(distinct from AWS credentials\) in ~/.aws/sso/cache/. This token represents the user's session with the Identity Center IdP and has a fixed duration \(default 8 or 12 hours depending on the IdP configuration, up to 90 days\). When this token expires, the AWS SDK or CLI cannot call sso:GetRoleCredentials to assume the target IAM role specified in the profile. The error manifests as 'UnauthorizedException: Session token not found or invalid' or 'The provided token has expired'. The fix is to run 'aws sso login --profile ' \(or 'aws sso login' if using sso\_session in config\) to re-authenticate with the IdP via browser, which refreshes the cached access token with a new expiration. Alternatively, configure the 'sso\_session' block in ~/.aws/config with 'sso\_registration\_scopes' and 'sso\_start\_url' to centralize session management.

Journey Context:
You have an AWS profile configured with sso\_start\_url pointing to your company's AWS Access Portal and sso\_role\_name set to 'Developers'. Your Python script using boto3 ran perfectly yesterday evening. This morning, it fails immediately with 'botocore.errorfactory.UnauthorizedException: An error occurred \(UnauthorizedException\) when calling the GetRoleCredentials operation: The provided token has expired'. You check ~/.aws/credentials - it's empty, as expected for SSO profiles. You check ~/.aws/sso/cache/ and find a JSON file with an 'expiresAt' field showing a timestamp 10 hours ago. You realize the SSO access token \(the one representing your login to the AWS portal\) has a 8-hour TTL and expired overnight. You run 'aws sso login --profile dev-sso', it opens your browser, you authenticate with your corporate IdP \(Okta/Azure AD\), it redirects back. The CLI writes a new cache file with a future expiration. You rerun your Python script; boto3 finds the valid SSO token, calls sso:GetRoleCredentials to assume the IAM role, retrieves temporary AWS credentials \(AKIA...\), and the script executes successfully.
