Error: "Failed to execute 'getComputedStyle' on 'Window'" #300

Closed jonschlinkert closed 2 months ago

jonschlinkert commented 7 months ago

It seems like the error happens randomly, but I'm sure it's related to something I haven't been able to figure out yet. 

Uncaught TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'.

I'm using React 18, and I'm also not rendering the component on the server.

Sorry to hear that you're seeing this. This isn't going to be enough to go on for me to help though. If you're able to narrow down a repro, let me know.

Uncaught TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'.

FWIW I think this generally indicates that you're passing undefined to getComputedStyle – which I think would mean that the register drag handle element is missing, but I'm not sure how that would be possible given the code.

I'm not using getComputedStyle. I am using a hook though, to check if window exists to prevent SSR in an attempt to fix this issue. But that doesn't work. I'm open to suggestions.

Sorry. I didn't mean "you" literally. I just meant, generally speaking, that error suggests that a value of undefined is being passed to getComputedStyle– which this library uses. I don't know how that would be possible though, looking at the code. I'll need a repro.

Going to close this issue as stale because it's been open for a long time in a "needs information" state. If we get more info on how to repro it, we can revisit it.
