Custom Functions > Test Function > Error messages vanish after 15 seconds

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

When testing a custom function, an error message opens in a toast. The toast goes away after 15 seconds, even if user is currently interacting with it.

Expected Behavior

The error message should persist until either:

• dismissed by the user
• user navigates to different area of app

Steps to Reproduce

1. Create a custom function
2. Introduce an error to the custom function input (or run a test on a custom function that does not support tests)
3. Observe error for > 15 seconds

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Hi! I'm sorry you're experiencing this issue.
I've reviewed the error and understand that this is expected behavior. However, I do see your point, and I will share your concern with the team to see if there's a possibility of changing this behavior.
If I receive any updates, I will let you know.
