The code below gives
Uncaught Error: You must pass a component to the function returned by connect. Instead received undefined
In my case it was Expo server that sometimes doesn't catch filesaves on Windows (probably) and it was seening old version of the component I've tried to connect (I had no export there yet probably). Re-saving my component without really touching anything fixed the issue.
Restarting Expo server with cleaned cache would probably help as well.
