Why doesn't the state come to connect()()?

Question

React

I have a store, with a reducer, in which, by clicking on a button, I will dispatch the corresponding action. Everything works here.
Then I sign the other component like this:

const matchStateToProps = (state)=>{
  return {
    title: state.title,
    text: state.text
  }
}
export default connect(matchStateToProps)(Notes)

This code fails with an error

TypeError: Cannot read property 'title' of undefined

, the error is in

return {
    title: state.title,
    text: state.text
  }

Of course, I can check for state:

const matchStateToProps = (state)=>{
        if(!state) return {}
  return {
    title: state.title,
    text: state.text
  }
}
export default connect(matchStateToProps)(Notes)

And it does work, but it shouldn't.
store code:

import {createStore} from 'redux'
const notesReducer = (state = {text: "", title: ""}, action)=>{
  console.log(state)
  switch(action.type){
    case "ADD_NOTES":
      return {...state, "text" :action.text, "title":action.title}
    break;
    case 'NOTE_DID_LOAD':
      return {state}
    break;
    default:
      console.log("Unreal dispatching ", action)
  }
}
export default createStore(notesReducer);

PS In the matchStateToProps function, I output the state variable to the console, there is empty space at the first moment of time, although it should not be, did I set the initial state?

Answer 1

default:
  return state;

By default, the reducer should return the unmodified state.
The first argument to connect is properly named mapStateToProps
