Success… thanks so much for your help!
I noticed in Developer Tools that the GetByID request was no longer happening. So I removed the response parameter and added it in again. From what I can see there are no differences but it now works. I read in another of hmwillet’s posts where she mentions that you can do this without a dataview and just use actionResult, but I couldn’t get that to work. I must be missing or misunderstanding some detail.
