Hubspot Server Tag - update contact not possible

Hi!

I was playing around with the Hubspot Tag to update a contact in Hubspot.

In Hubspot, when looking at the API Call Log, I see this error:

{"status":"error","message":"Contact already exists. Existing ID: 107759274188","correlationId":"3b139984-8d90-4c61-be56-36721a36639a","category":"CONFLICT"}

I dont understand, as the Tag should either create or update the contact. So why do I get this conflict, when it should be updating if the contact already exists?

Cheers

Do you have any new data on this contact that can be updated?

Yes, 2-3 contact properties, which are created in HS, correct internal labels used and accessible via the private app.

I’ll probably ask HS Support.
