I can confirm I also get this error. Did lots of debugging, but can't figure it out. Glad it's not just me, and thus looks less likely to be my code.
The error is from backend.js and goes away if I disable the vue devtools extension, so we know its the devtools plugin, not one generated by the vue application.

Is there a solution for this? I also encountered the same problem.

I tried several things, including wondering if it was listeners that had not been removed before unmounting etc, but nothing changes. For now I'm just trying to ignore the errors, but theres so many that fly up, it really affects development.

Would be nice if this issue could at least be acknowledged.

@deot Can you add the actual exception error message into the title, so that more people can come across this thread if they are searching for it via search engines? I only found this by manually checking the vue devtools issue page, and some people might not even realise its related to the vue chrome extension.

Suggestion for title:

Fantasic! That was quick @Akryum thanks!

Question though, looking at the PR, it seems mainly to remove errors on production builds with the try/catches, but doesn't seem to change much for non-production? Unless I missed something? I'll look forward to updating and trying anyway.
