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

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.

Any ideas?

@PCguru Did you resolve this issue?

I'm having the same issue. Did anyone find a fix for this?

We've moved to https://www.npmjs.com/package/react-native-fast-image, no longer using rn-fetch-blob.

Did not find any solution all the way up to React Native 0.57 and about 50% of app crashes were related to rn-fetch-blob.

Did anybody find a fix?
I am using version 0.12.0 and RN 0.62.2.

The error occurs only when I restart the app programmatically (using react-native-restart).
