Updating redux slice with multiple values-CodePudding

I am using a redux slice in a react project to store information about the current user. However, I am getting the following error when loading the page:

TypeError: Cannot read properties of undefined (reading 'name')

Dashboard.js:

export function Dashboard() {
const currentUser = useSelector(state => state.currentUser);
const dispatch = useDispatch();

return (
   <div>
      <p>{currentUser.name}</p>
      <p>{currentUser.description}</p>
   </div>
   <Button onClick={() => dispatch(setCurrentUser(name, description))}>Set user</Button>
);
}

currentUserSlice.js:

import { createSlice } from '@reduxjs/toolkit'

export const currentUser = createSlice({
  name: 'currentUser',
  initialState: {
    name: "",
    description: ""
  },
  reducers: {
    setCurrentUser: (state, action) => {
        return state =  {
            name: action.payload.name,
            description: action.payload.description
        }
    }
  }
})

// each case under reducers becomes an action
export const { setCurrentUser } = currentUserSlice.actions

export default currentUserSlice.reducer

store.js:

import { configureStore } from '@reduxjs/toolkit'

import currentUserReducer from './currentUserSlice'

export default configureStore({
  reducer: {
    currentUser: currentUserReducer,
  }
})

Update I did not properly import the reducer into store.js. However, the dispatch is not updating the data now that I have imported it

CodePudding user response：

You are sending two values in your payload instead of an object. Please update your dispatched function to send an object instead:

export function Dashboard() {
const currentUser = useSelector(state => state.currentUser);
const dispatch = useDispatch();

return (
   <div>
      <p>{currentUser.name}</p>
      <p>{currentUser.description}</p>
   </div>
   <Button onClick={() => dispatch(setCurrentUser({name, description}))}>Set user</Button>
);
}
