Incorrect status code in POST /artifacts/{parentId} endpoint

[Celiant]

In case when user sends broken body for /artifacts/{parentId} endpoint(for example valid file without "artifacts" key) he get 201 status code(success)
Also, if user sends invalid parentId he can't see that something wrong with parentId

1. Create request to /artifacts/{parentId}
2. In body don't use "artifacts" key in formdata
3. Use wrong parentId(optionally)
4. Send request

422 status code with "There is no appropriate policy or policy is not in DRAFT status" message(invalid parentId)
