Navigator API errors are being rethrown as generic errors

[Nanosync]

What happened and what did you expect to happen?

We are currently catching error names and handling them by a switch case when calling functions listVideoInputDevices, listAudioInputDevices, chooseVideoInputDevice, chooseAudioInputDevice. However, the chime JS sdk rethrows errors leading to generic errors, although the error.message property is preserved. In the handleGetUserMediaError function, the base error GetUserMediaError doesn't preserve the original error.name property.

Reproduction steps

Disable browser audio/video permissions then call any of the listed functions above. The functions that throw GetUserMediaError or a subclass of it has the error.name property Error although the original error name was more specific.

I created PR #1815 to address this issue but for now you can check the error name via error.cause.name.

catch (error) {
  if (error instanceof GetUserMediaError) {
    // Use error.cause?.name to access an Error name and error.cause?.message to access the original error messasge.
  }
}

@Nanosync Would the PR #1815 solve your use case? We will return the class name instead of the generic Error name?

PR #1815 has been merged so close this.

Hi @ltrung, yes, it will solve the issue. Thank you!
