Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
I use "react-router-redux": "^4.0.8", same error. Change version to "react-router-redux": "^5.0.0-alpha.9", then it's fine
yarn add react-router-redux@next
yarn add @types/react-router-redux@next
