TypeError: undefined is not an object (evaluating 'array.reduce')

[tehjnito]

this error gets thrown using my own code and even with the example provided.
I'm assuming it has something to do with that method in the utils files, but I'm uncertain.

Demo code is working fine for me. Just tested.

This error would happen if you are not passing a valid array as the items prop. Please check again.

i can repro the issue :
in my case :

this caused by you install this super grid module, but you forgot to re run react-native run-android

so the react native didn't know the module yet..., solve by re run react-native run-android , done 🎉
