Thank you for the fast reply 🙂 @bitter-branch-40324 1) This is the very first part of a very complex detector flow where on the each stage I do complex extraction of the set of fields from the input at once with GPT (instead of multi-entities filling I want to be able to extract several fields from the input at once in a human natural way like one message "Hello my name is Vlad, I want to buy house for 1m$" shoud fill 4 fields at once). But it does not work even for this basic case 🙂 2) It should work in my case because event.preview == event.payload.text 3) It is so confusing that there is no straight-forward way to add in debug what was the exact GPT input and what was the exact output. Is there ANY way to log this info? 4) It does not work even with your suggestion (see screenshots)
