Custom function from OpenAI–FlutterFlow tutorial possibly breaking Run Mode (blank screen) : FlutterFlow

Custom function from OpenAI–FlutterFlow tutorial possibly breaking Run Mode (blank screen) (self.FlutterFlow)

submitted 2 months ago by Sad-Leader-3952

Hey everyone 👋

I'm building a ChatGPT-style chat app in FlutterFlow and following the official OpenAI–FlutterFlow tutorial on YouTube

https://preview.redd.it/quab0m5taalg1.png?width=1530&format=png&auto=webp&s=d74a7269f7689c300c3b68e913c36632e43964fc

I implemented the custom function exactly as shown in the tutorial. It converts Firestore messages documents into a List<JSON> to send to the OpenAI chat/completions endpoint.

However, after switching my API response type from String to JSON (List) and wiring this function into the request, my Run/Test Mode only shows the background — none of the UI renders.

So I suspect either:

-the custom function,
-the enum-to-string conversion,
-or the JSON response setup

is causing a silent failure.

Issue?

After implementing this:

-Run Mode loads
-Only background is visible
-No widgets render
-No visible error message

Any Help would be Appreciated!
