422 Deal has no primary contact

The activity could not be logged because the deal has no primary contact to anchor it to. Every activity row is attached to a person as well as a deal.

Retry only after changing the request

What causes it

• The deal was created without primaryContactId and no contact has been attached since.

How to fix it

• Create the person with POST /contacts (or find them with GET /contacts?email=), set primaryContactId on the deal with PATCH /deals/{id}, then retry.

`type` is stable and safe to branch on in code. `detail` is specific to your request and is the field to read for the particulars; its wording may change.
