Question on Unhandled Runtime Error

[rf2332]

Hi all- At first I ran my app, it worked. But after adding some new features, it popped up this error when I clicked a button (which previously worked and is to store frontend data in backend). And even I reversed all my changes, deleted my .pycache, this error still shows up. Have any of you encountered this issue before?

ENG-4254 Question on Unhandled Runtime Error

The error is a random frontend error caused by grid.js, we don't really have much to work with here :/ you can restart reflex and if that doesn't work you can try reflex init to regenerate the .web folder.
