Tried to access a JS module before the React instance was fully set up #26

Description

@fgeorgsson
  • please provide the version of installed library and RN project.

react-native-fetch-blob@0.10.8 through react-native-cached-image@1.4.0.
react-native@0.47.2

Our app use react-native-cached-image to cache a bunch of images. Some are proloaded early on, when the app is rendered the first time.

Sometimes when the app starts, perhaps after a code-push, we get the error message below logged to Fabric. The app crashes.

I am pretty sure it only happens after a code-push is downloaded and the new js-app is restarted, but I'm not sure. It does not happen every time though, seems pretty rare, like 1/100 times a code-push is applied.

Fatal Exception: java.lang.RuntimeExceptionTried to access a JS module before the React instance was fully set up. Calls to ReactContext#getJSModule should only happen once initialize() has been called on your native module. Raw Text
