Description

Getting this error after latest update:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object. You likely forgot to export your component from the file it's defined in. Check the render method of `AwakeInDevApp`.

Expected Behavior

I setup a basic application using Redux.

Observed Behavior

I am unable to render the application in Expo because of this error.

If there's an error message, please paste the full terminal output and error message in this code block:

Thanks for the detailed report and the reproduction! It looks like your App.js no longer exports a default component after your redux changes, and it also looks like you've added your own call to AppRegistry, which should instead be handled by CRNA. Can you try following the template and see if that fixes this?

[mwq27]

Yep, that was the problem. I removed that AppRegistry call and exported the component instead.

Thanks

Awesome!

what template? I looked at https://github.com/mwq27/rn-poc/blob/master/App.js and it looks like you have AppRegistry. I'm confused
