Property cannot be missing or null

[mclayton]

I am trying to create contacts.
One set of data works fine, the latest set doesnt work.

Here is my response string:
{"status":"error","message":"property cannot be missing or null","correlationId":"d18f6aff-3a52-4a67-821f-72e28a30e7de","requestId":"6fa7f8c46081f6cf61815ced37f87043

All of my property fields are set.
What is the problem, what is missing?

Hi @mclayton,

Can you post the full request you’re making so that I can take a closer look?
