# Troubleshooting
<a name="troubleshooting"></a>

If a deployment fails, follow this resolution process:

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

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

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

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

1. 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.
