Redux createSlice not working for me

1

I used the folowing code for reduce createSlice :
// import { createAction , createReducer} from “@reduxjs/toolkit”;
import { createSlice} from “@reduxjs/toolkit”;
// export const bugAdded = createAction(“bugAdded”);
// export const bugResolved = createAction(“bugResolved”);
// export const bugRemoved = createAction(“bugRemoved”);
let lastId = 0;
const slice = createSlice({
name: “bugs”,
initialState: [],
reducers: {
bugAdded: (bugs, action) => {
bugs.push({

            id: ++lastId,
            description: action.payload.description,
            resolved: false,
        });
    },
    bugResolved: (bugs, action) => {
                const index = bugs.findIndex(bug => bug.id === action.payload.id);
                bugs[index].resolved = true;
    },
    bugRemoved: (bugs, action) => {
       bugs.filter(bug => bug.id !== action.payload.id);
       
    }
}

});
and get following error what is the fix for this:
redux-toolkit.esm.js:279

   Uncaught Error: "reducer" is a required argument, and must be a function or an object of functions that can be passed to combineReducers

I found what was missing:
once i added the following it worked:
export const { bugAdded, bugResolved, bugRemoved } = slice.actions;

export default slice.reducer;
