the onErrorCaptured() hook is not working as expected

[HermitSun]

I tried to use the the onErrorCaptured hook just as I used it in 2.x: code in CodeSandbox , outputs are in console.

The result is not in line with my expectation. Actually, the error was not captured, and because I usedVue.config.warnHandler, I found that the error was treated as a warn, onErrorCaptured was not called. But if I used it as 2.x, using errorCaptured hook, it works properly. Did I get something wrong? Thanks.

And sorry for my poor English.

In fact, we don't have the onErrorCaptured hook now.

OK. Thank you.
