React error boundary errors are not actually sent

Following the docs here https://github.com/airbrake/airbrake-js/tree/master/packages/browser/examples/react

I tried adding params to the notify call but they never showed up in Airbrake. I then discovered that they aren’t sent in the network API call either. Further digging revealed the following:

1. window.onerror is being called before the React error boundary is being called
2. When the error is caught by the error boundary, it tries to notify again. However, there is a filter built in called makeDebounceFilter that prevents the React error boundary error from actually being sent

So, it appears that you either need to turn off window.onerror for React apps or find another way to report the errors caught by error boundaries?

@frehner can you elaborate on how did you fix this?

Things are looking good after cleaning some stuff up. I’ll close this for now; thanks for your help.
