Troubleshooting

If a deployment fails, follow this resolution process:

  1. Check Amazon CloudWatch Logs for specific error messages related to the failed stack operation.

  2. Verify IAM permissions and role assignments for the deployment account.

  3. Review the deployment_map.json configuration for correct version constraints, account IDs, and Region values.

  4. Validate the CloudFormation template syntax by using the CloudFormation Linter (cfn-lint).

  5. If the issue persists, roll back to the last known good version by updating the version constraint in deployment_map.json to the previous commit ID.
