fallback not work

[ipy]

In raven.js of the raven-js lib, _drainPlugins is in install method while the globalOptions assignment is in config. So _globalOptions.transport won't be assigned to globalOptions.transport.
When native not available, it will use the default transport in raven.js instead of which in the react-native plugin. and because

1. hasCORS is false
2. Content-type header not set

the request will not send.

Hey,
sorry, I think I don't fully understand the problem.

We set the transport here if the native plugin isn't available:
https://github.com/getsentry/react-native-sentry/blob/master/lib/raven-plugin.js#L81
and raven-js fetches the transport before every send:
https://github.com/getsentry/raven-js/blob/master/src/raven.js#L1583

So can you give me an example code/config which does not work?

[ipy]

import { Sentry } from 'react-native-sentry';
Sentry.config('xxx').install();
Sentry.captureMessage('test');

Sorry for my bad expression... As you mentioned:
https://github.com/getsentry/react-native-sentry/blob/master/lib/raven-plugin.js#L78

if native support is not available, options.nativeClientAvailable && options.nativeClientAvailable === false will always be false because options.nativeClientAvailable is false, the transport is not set.

You may set a breakpoint in the _transport method in raven-plugin.js, and may notice it will never be reached.
It uses the original method of raven.js. In more recent version of react-native the method will work, but we are using react-native 0.42 and withCredentials of xhr is not added yet, the request will never be sent.

Hey, this should be fixed in 0.17.0
