Solution: 
// slice
export const authAPI = createApi({
    reducerPath: 'authAPI', // use this one will solve the problems
    endpoints: (builder) => ({})
    baseQuery: fetchBaseQuery({})
})

// store.js 
export const store = configureStore({
    reducer: {
        [authAPI.reducerPath]: authAPI.reducer,
        [projectAPI.reducerPath]: projectAPI.reducer,
    },
    middleware: (getDefaultMiddleware) => [
        ...getDefaultMiddleware(),
        authAPI.middleware,
        projectAPI.middleware,
    ],
});
