dealCustomFieldData/bulkCreate always responds successful

I’m updating deal custom fields using a bulkCreate. However, regardless whether the bulkcreate actually works on not, it always reports "The bulk insert was successful.

I’m using c# with RestSharp, but I can repeat this using Postman.

It’s not very helpful thinking your update has worked and yet nothing is updated!

Really sorry about that. Totally agree. We plan to improve our API error responses in the future.
