using $watchAsObservable, and using throw new Error() watch not work

[reaink]

using $watchAsObservable, and using throw new Error() watch not work, the watch will become invalid. Even if catchError is used, it will no longer watch. Is there a way to wake up this watch?

使用$watchAsObservable后，再使用throw new Error()抛出错误后，watch 就会失效，即使有使用catchError 它也将不再进行watch ，请问有没有办法继续执行这个watch，不去理那个error ，我自己在catchError 中弹出错误提示

Hello @nshusr
It seems you want continuation on error, you need catchError and emit an EMPTY Observable in catchError callback
