When you make a document generation request, it might fail at the request stage or during document generation.

## Request stage errors

While request failures are rare, the following table describes possible error scenarios and how to troubleshoot them.

| <strong>Response code</strong> | <strong>Type</strong> | <strong>Issue</strong>                                        | <strong>Solution</strong>                                                                                                                       |

## Document generation stage errors

After Doc Gen validates the request and initiates document generation, failures can occur during processing. To troubleshoot these errors:

1. Check the [status of the document generation activity](/en/box-doc-gen/tracking-and-troubleshooting/document-generation-statuses).
2. [View the activity details](/en/box-doc-gen/tracking-and-troubleshooting/tracking-document-generation-activity) for the failed request.
3. Review the error information and JSON data used in the request.

## Box security limitations

If document generation fails due to access restrictions, verify that Box Shield classification policies are configured correctly. Doc Gen requires access to templates to generate documents. If a Box Shield classification policy restricts access to a template, document generation will fail. For more context, see [Box security limitations](/en/box-doc-gen/box-doc-gen-templates/box-doc-gen-limitations).
