Uncaught TypeError: Cannot read properties of undefined (reading 'getTopStartCorner')

Getting help Issues

I occasionally see this error in my console. (See attached screenshot.) I have not found a way to reliably reproduce it, but it seems a bit of defensive code on your end would clear it up. We are on 15.3.0.

Hi @dhaber

I do not see any similar reports on our Github issue board.

We can see that it comes from the mouseover hook while using nestedHeaders. Do you get it when you perform such an action? Any details regarding steps to replicate the issue and a demo would help us much as with no related reports and our nestedHeaders demo showing no errors there’s not much I can do to help.

Hi @aleksandra_budnik,

Understood. Next time it happens I’ll spend more time to see if I can isolate what series of steps triggers it.

Thanks.
