Connect can still swallow errors

[Nantris]

What version of React, ReactDOM/React Native, Redux, and React Redux are you using?

• React: 18.1.0
• ReactDOM/React Native: N/A
• Redux: 4.2.0

What is the current behavior?

Errors are swallowed inside of mapStateToProps sometimes. I'm not sure of the exact circumstances to recreate this.

What is the expected behavior?

Errors are never swallowed

Which browser and OS are affected by this issue?

Electron 18

Did this work in previous versions of React Redux?

• Yes

Quoting my original comment on another issue:

@markerikson is this believed to be fixed at this point? It seems not to be, or at least - I have no other theory for why our errors are getting swallowed inside of our mapStateToProps.

I've spent an hour trying to pinpoint the exact cause for us, and this issue is my only lead.

Specifically, this component uses forwardRef - so I wonder if that could be related? Version 8.0.4. I discovered this when I accidentally typed 'some text'.contains('') instead of 'some text'.includes('') and everything broke, but no error appears.

If I call the function from anywhere else, or manually from console - the errors appear as expected.

The only other thing that's really even remotely of interest that I can see is that the function that's called is memoized.

I've seen errors properly logged from mapStateToProps plenty of times - but it just won't work here. Coincidentally, this is one of only four components we have with forwardRef: true.

I was able to test with forwardRef: false and excluding the 3rd/4th arguments for connect but the issue persists.

I did ask for this new issue to be filed, and I appreciate that you did that.

But honestly, we have no real plans (or time!) to make further changes to connect at this point.

If anyone ever wants to take a stab at this, or can provide a Replay ( https://replay.io/record-bugs ), I can take a quick look. But until then, I'm going to close this.
