Answer doesn't match with entity values

I am having the same issue. Have we found any solution ? As per my understanding When Form is active it should expect and accept user Input as a slot value, but instead it takes it as another intent. I have one usecase where I want to take server name as an user input while Form is active and get the response via backend python APIs. There could be thousands of servers and all can’t be defined or added in NLU.yaml as ‘server name’. I don’t want to implement button based bot. I am trying to resolve this via Regex.

Any solution please suggest
