I've been using the REST driver ( for quite some time to add users to the Adobe cloud service using the Adobe User Management API. I have been using custom ADD, DELETE, and QUERY handlers with no issues.

I have just added a new MODIFY custom handler and when it starts up I get an error stating that the URL is "Missing <association> placeholder in the URL". If I add the placeholder "<association>" to the URL it starts up correctly. The problem is that I don't want the association in the URL. The user ID is managed through the JSON data in the body. Is this a bug or something I can work around?
