TypeError: undefined is not an object (evaluating 't.exception.values[0].stacktrace.frames')

What is the current behavior?
I am using raven-js with a react-native app to report errors and crashes. TypeError is thrown while reporting errors received from some third party libraries. For me, it is happening while reporting errors thrown by Firebase Javascript SDK. Firebase provides a promise based API in which I log the errors directly to Sentry. For e.g.

firebaseRef.update(obj).catch(error => {
  Raven.captureException(error)
})

When an error is thrown by the above call, instead of seeing the error, I see below error on Sentry

I guess the error object doesn't have a stack trace but in such cases, just the error should be recorded.

What is the expected behavior?
No TypeError should be thrown and the correct error should be recorded.

Which versions of Raven.js, and which browser and OS are affected by this issue? Did this work in previous versions of Raven.js? Are you using the CDN (http://ravenjs.com)? Are you using hosted Sentry or on-premises? If on-premises, which version (e.g. 8.7.0)?

raven-js: 3.7.0
react-native: 0.37

Hi, Any updates on this issue? Is the reported behavior expected? Thanks!

I haven't been able to investigate yet. In the meantime, I recommend coercing the Firebase error object into a string or something non-Error like.

Thanks for the reply @benvinegar . Just wanted to know if the reported behavior is expected and looks like it is not. I will change the Firebase error object into a string in the mean time as you recommended.

@varungupta85 – is it possible you could put together a simple Firebase example I could use to debug this? I haven't used Firebase in years and I'm going to need some help to move on this.

hi @benvinegar do you mean a complete react native app that you can readily run on a simulator or just some sample firebase code (with instructions) that you can plug into your test app?

React-native plugin will be soon deprecated. Please use https://github.com/getsentry/react-native-sentry from now on.
