[bug\_fix] botocore.exceptions.TokenRefreshNeeded: The SSO session has expired or is invalid / Error: The security token included in the request is expired \(when using SSO profiles\)

Execute \`aws sso login --profile \` to re-authenticate with IAM Identity Center and refresh the temporary credentials cached in ~/.aws/sso/cache/. The AWS SDK uses the cached SSO token to call CreateToken and then AssumeRole; when the SSO token expires \(default 8-24 hours\), the SDK cannot auto-refresh without interactive re-authentication via browser/device flow. Root cause: AWS SSO uses OIDC to obtain temporary credentials that expire, and the SDK lacks a refresh token capable of silent renewal without the user's OIDC session.

Journey Context:
Developer has a Python script using boto3 with AWS\_PROFILE set to 'dev-sso'. Yesterday it worked perfectly. Today, running the script throws TokenRefreshNeeded or 'The security token included in the request is invalid'. They check ~/.aws/credentials but the profile isn't there \(SSO doesn't store long-term credentials there\). They check ~/.aws/config and see sso\_start\_url and sso\_region. They try \`aws sts get-caller-identity\` and get the same error. They realize the SSO session expired. They run \`aws sso login --profile dev-sso\`, which opens a browser to the AWS access portal. After logging in and approving the client, the CLI caches the new token. The script now runs successfully.

environment: Local development environment using AWS IAM Identity Center \(SSO\) for authentication; typically on macOS/Linux with AWS CLI v2 configured for SSO. · tags: aws sso iam-identity-center token-expired boto3 botocore refresh-credentials sts · source: swarm · provenance: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-sso.html
