React Native: Does not send exceptions at all

[grabbou]

On a side note - we should really improve the way we call onError callbacks - without original error or at least request response it's really hard.

Anyway, after putting console.log inside request.onreadystatechange in react-native plugin, I've seen all requests on Android fail with statusCode: 0 and body: "Payload is set but no content-type header specified".

Simply adding:

request.setRequestHeader('Content-type', 'application/json');

fixed the issue and errors started appearing in dashboard immediately.

It seems to me like it's a RN change as it used to work last week before upgrade.

Interestingly I just ran across this same issue.

@grabbou – thanks for your investigation. I've submitted #527 which should address this.

There's a broader issue here, I think, at least in 0.22. I now have to explicitly supply a Content-type header to fetch(), at least in dev mode, when I did not have to previously and don't have to iOS.

That's already fixed (not sure if pushed), check recent pull requests :)
