We missed this as part of #1515

[tmeasday]

We need to check for the channel exception on both sides of the channel.

Issue:

Our RN examples were broken on master (I guess RN was broken in general).

What I did

@ndelangen's change to check the channel on the manager side.

How to test

# clean properly
npm i && npm run bootstrap && npm run build-packs && npm run bootstrap:react-native-vanilla
cd examples/react-native-vanilla
npm run storybook
# check no exception in browser

react-native run ios
# check works
