Current Behavior

Seems like it doesnt affect anything in behaviour but the error appears en chrome debug console. The problem seems related

Expected Behavior

No error should appear in debug console

Steps to Reproduce

PROJECT:

1. make a new project with 2 pages (home, child)
2. inside home, make a button (go to child)
3. the child page should have back button in appbar
4. in child create a form validation with a field (for numbers/digits only) and a button for sumbit
5. the submit button should validate and after that must navigate back

TEST:

1. run the test project
2. click "go to child"
3. write a number like "10" in the text field
4. click "submit simulation"
5. The error appears in console (it is weird, sometimes it doesnt appear)
6. Sometimes it appears when i click "<- back button"

I have also experienced the same issue, and would like to see it fixed, or at least caught.

Hi @OldFred2023 - Thanks for highlighting this observations. We are aware about it. We advise ignoring this error right now because it is not affecting any functionality. Thanks

@hariprasadms We are facing this error as well, and while it's not per se affecting functionality right now, it is pretty significantly impacting performance in our app. This most apparent on lists with custom user card components for example, and those user cards contain multiple other components as well. When loading a page with such a list, there is a pretty significant lag. It hangs for a second (or more) in a half loaded state before continueing.
