Why can’t the posts made by the user be displayed?

In the backend I can use my Token to search after Notes which User creates.
In my Frontend project it doesn´t show me my Posts ..

I store my token in localStorage “userInfo” .. so it can be taken from there if I login to my account.

my NotesSchema :

const forumSchema = ({
    forumName: {
        type: String,
        required: true,
    },
    forumDescription: {
        type: String,
        required: true,
    },
    createdBy: { 
        type: Schema.Types.ObjectId, ref: 'User' 
    },
    published_on: {
        type: String,
        default: moment().format("LLL")
    },
});

My note route :

router.get('/getByOwnerID',verifyToken,ForumService.getByToken);

And the function which I wrote for that :

exports.getByToken = async (req, res, next) => {
  Forum.find({ userID: req.token.userID }) 
  .then(doc => {
      if(!doc) { return res.status(400).end();}
      return res.status(200).json(doc);
  })
  .catch(err => next(err));
}

And the frontend noteAction.js:

export const listNotes = () => async (dispatch, getState) => {
    try{
        dispatch({
            type: NOTES_LIST_REQUEST,
        });
        const {
            userLogin: { userInfo },
        } = getState();

        const config = {
            headers: {
                Authorization: `Bearer ${userInfo.token}`,
            },
        };

        const { data } = await axios.get(`http://localhost:8080/forum/getByOwnerID`, config);
        
        dispatch({
            type: NOTES_LIST_SUCCESS,
            payload: data,

        });
        }catch(error){
            const message = 
                error.response && error.response.data.message
                    ? error.response.data.message
                    : error.message;
            dispatch({
                type: NOTES_LIST_FAIL,
                payload: message,
            });
        }
    }

I hope it´s clear if not I can add Information ..
