The error "Cannot read properties of undefined" in relation to the 'type' property can be resolved in Redux toolkit by ensuring that the action object being dispatched has a 'type' property. If the 'type' property is missing or mistyped, it can cause this error.
One way to ensure that the 'type' property is correct is to use the createAction function provided by Redux toolkit. This function automatically generates a type string and a corresponding action creator function, which ensures that the 'type' property is defined correctly.
For example:
import { createAction } from '@reduxjs/toolkit';
const addTodo = createAction('todos/add');
dispatch(addTodo({
text: 'Buy new shoes'
}));
In this example, the 'addTodo' action has a defined 'type' property of 'todos/add', which ensures that the error is not thrown.
