Uncaught TypeError: Cannot read property 'apply' of undefined in Google Chrome

Hi,
I am new to Reac&Redux app.
I use create-react-app but sometimes i have error in google chrome

Uncaught TypeError: Cannot read property 'apply' of undefined

after restart the google chrome, app works for me

in other browsers do not have this error

This is not a problem with Create React App itself. As you can see it throws inside configureStore so you’re likely passing something invalid to it. For example, maybe you use Redux DevTools and pass undefined to compose() or something like this. It’s hard to say without a code example, and I’ll close since it’s not specific to Create React App, but feel free to continue the discussion or link to a failing project that can reproduce this.

I had the same problem and I could solve it with the info in this two links When browser doesn't have the redux devtools extension the app throws an undefined error Y Advanced store setup
