What does your problem relate to?

The problem seems Module related

React-Unity-WebGL Version

9.2.1

React Version

17.0.2

Unity Version

2022.2.9f1

What happened?

Version 8.x.x. of the package supported error listeners: https://github.com/jeffreylanters/react-unity-webgl/blob/7b7aac91690b7cd3ed7968e82b20c9f732b04c43/documentation/versioned_docs/version-8.x.x/api/on-error.md#L4 .

When trying to implement an error listener on Verizon 9.2.1 using the addEventListener(‘error’) API, it appears that no errors are caught detected. Is this intended behavior or is there an undocumented API that captures the proper usage of the error event listener?

Thanks!

Hi Avinash! Sadly Unity doesn't expose caught errors that well, they're instead using window.error to dump their errors to the console without any proper way to interfere. Previous versions of the module intercepted these error messages, but this was proven to be too hacky of a solution. -- So until Unity implements proper error handling, there isn't anything we can do really.
