title: Form Gateway Errors
description: Additional error codes specific to the Moveworks Forms Gateway
---------------------------------------------------------------------------

In addition to the [standard gateway errors](/api-reference/content-gateway/content-gateway-errors), if you're implementing a form gateway, you should implement the following error codes as well.

### 400 `FORM_OUT_OF_DATE`

Moveworks submitted a form which is no longer valid since it has been updated in the source system.

```json
{
  "error": {
      "code": "FORM_OUT_OF_DATE",
      "message": "This form was last updated on 2022-10-20T07:00:00Z which is after the ingestion metadata date (2022-10-19T07:00:00Z)"
  }
}
```

<Note>
  If you surface this error code, Moveworks will gracefully handle it by linking your employees to the latest version of the form.
