3DMS Request Deduplication: Design ID in Error

When attempting to create a 3DMS design request for a project with an in-progress 3DMS request, you'll now receive not only an HTTP 422 error message but also the design id of the offending request.

{"A design request already exists for this project",
meta: {"design_request_id": "3fa85f64-5717-4562-b3fc-2c963f66afa6"}}
