I have more success. After some research I am getting accounts coming in but only if I limit the number of calls.
I started with $.Entity.UsrIdLst[:70].Usr and it failed. I think went small and did $.Entity.UsrIdLst[:10].Usr. It worked. I then increased it up to 70 slowly and it’s working.
This obviously cannot be the desired method. What could be limiting my requests? Is there by chance a trottle on the endpoint?
