I'm trying write reducer for ticket object in my app and I use createSlice for it like this:

    export const ticketSlice = createSlice({
    name: 'ticket',
    initialState: { value: null },
    reducers: {
        ticketSet: (state, action) => {
            state.value = action.payload;
        },
        ticketSetCategory: (state, action) => {
            state.value.category = action.payload;
        }
    }
});

Everything works fine but it's not so convenient to use state.ticket.value in useSelector. I prefer state.ticket instead it. So I changed my reducer like it:

    export const ticketSlice = createSlice({
    name: 'ticket',
    initialState: {},
    reducers: {
        ticketSet: (state, action) => {
            state = action.payload;
        },
        ticketSetCategory: (state, action) => {
            state.category = action.payload;
        }
    }
});

After that, the storage stopped working. The ticket value is always an empty object. What am I doing wrong?
