I am trying to insert records into Cases module in CRM. I am using the following restful URL to do it. If I try to insert data into a custom field it errors and gives me a 4500 error code. (Internal error). If I do the default fields it works fine. 

This is the url I am using:

This will fail..

Can you insert into Cases using custom fields?
