Report #103466

[bug\_fix] AWS SDK or CLI fails with 'ExpiredToken: The provided token has expired' while using temporary credentials from STS AssumeRole.

Re-assume the role to obtain a new set of temporary credentials and update the environment variables \(\`AWS\_ACCESS\_KEY\_ID\`, \`AWS\_SECRET\_ACCESS\_KEY\`, \`AWS\_SESSION\_TOKEN\`\) or the SDK's credential provider. For long-running workloads, configure automatic role refreshes using the SDK's assume-role credential provider instead of exporting static STS credentials.

Journey Context:
You export \`AWS\_ACCESS\_KEY\_ID\`, \`AWS\_SECRET\_ACCESS\_KEY\`, and \`AWS\_SESSION\_TOKEN\` from \`aws sts assume-role\` into your shell and start a long-running data transfer. Half an hour later every AWS call fails with \`ExpiredToken: The provided token has expired\`. You check the STS response you saved earlier and see \`Expiration\` was 3600 seconds after it was issued. Temporary credentials from STS are intentionally short-lived and AWS does not extend them; after expiration the token is rejected globally. You re-run \`aws sts assume-role --role-arn arn:aws:iam::123456789012:role/CrossAccountRole --role-session-name cli --duration-seconds 3600\`, export the new trio of values, and the workload resumes. To stop this from recurring you switch the application to use the AWS SDK's built-in \`AssumeRoleProvider\`, which automatically calls \`AssumeRole\` again before the old credentials expire.

environment: Shell session or application using exported STS AssumeRole credentials; the assumed role session reached its \`Expiration\` timestamp. · tags: aws sts assume-role expired-token temporary-credentials token-refresh aws-sdk · source: swarm · provenance: https://docs.aws.amazon.com/IAM/latest/UserGuide/id\_credentials\_temp.html
