You must pass a component to the function returned by connect. Instead received undefined

Question

The code below gives

Uncaught Error: You must pass a component to the function returned by connect. Instead received undefined

Answer 1

Not related to the asker specifically, but if you're facing this error, it's worth to check if you have the connect() syntax right:

const PreloadConnect = connect(mapStateToProps, {})(Preload);

export default PreloadConnect;

Note that Preload, is passed as a IIFE parameter.
