RN 0.43 bug

[OlegKovalSmartexe]

Yesterday i update RN in my project to 0.43 (from 0.40)

And today i get report in crashanalistics about crash with message:

"Fatal Exception: com.facebook.react.common.JavascriptException: undefined is not an object (evaluating 'u[n]'), stack:
getListener@95:1029"

No crash before..

Any ideas how to fix it?

[enieber]

when this occurred? in the start the app or when you running a specific page?

I am also seeing this. I get it occasionally after touching a TouchableWithoutFeedback or TouchableOpacity on android. RN 0.43.2

I'm not shure, but maybe you try to render numeric value like this: <Text>{n}</Text> (where n is a number variable).
I had code like this and it works before upgrade to 0.43. I changed code to <Text>{String(n)}</Text>.

[johndanek]

I'm getting undefined is not a function (evaluating '(0,l.combineReducers)({github:r(862).reducer,login:r(863).reducer,search:r(917).reducer})')

At a complete loss for what to do to get past this.

This only occurs when building a release APK for Android. Running a dev build works fine.

[dinzo]

@johndanek have you tried RN 0.44.3?

[johndanek]

@dinzo I believe this is an Ignite issue. I started a fresh project just using React Native (no Ignite), re-implemented my code, and don't see the problem anymore.
