Virtual Agent : How to fix "AI search fallback' topic error

[Jenfer Rithika]

Hello Good Day!

I have been facing this issue, 

And I have created a custom topic by integrating an OOB topic (AI search) using topic block, wherein my results aren't been returned, also had a test with the Action Flow, the results are been produced, but these results aren't been returned.

My suspect is on VA whether is there any problem with it or AM I handling it wrong?

Also had tested the api code on my background script the JSON results are been returned, the problem is with VA, so please give me a solution.

kind regards

Did you find the solution for it ? i'm too facing the same issue.

Yes, since when the AI search topic is not triggered, so if you have enabled AI search in Conversational Interface and Custom greetings, I think you need to look after this property which sometimes block AI search results due to heavy payload, "glide.cs.runtime.user_input_max_length" please make the value upto 1M.

If you're on Utah release and getting this error the recommended value for this property is at least over 75,000.
