redux react async-await redux-thunk JavaScript

I'm updating my dependencies and I need help solving Hey everyone, I'm running into an issue that's driving me crazy. I'm working with an scenario when trying to use `async/await` syntax within a Redux Thunk action creator in my React application. I'm using Redux-Thunk version 2.4.1 and React-Redux 8.0.0. I expect the asynchronous action to wait for the API response before dispatching the action to store, but it seems to dispatch the action immediately without waiting for the promise to resolve. Here’s a simplified version of my action creator: ```javascript import { createSlice } from '@reduxjs/toolkit'; import axios from 'axios'; export const mySlice = createSlice({ name: 'mySlice', initialState: { data: null, loading: false, }, reducers: { fetchDataStart: state => { state.loading = true; }, fetchDataSuccess: (state, action) => { state.data = action.payload; state.loading = false; }, }, }); export const { fetchDataStart, fetchDataSuccess } = mySlice.actions; export const fetchData = () => async dispatch => { dispatch(fetchDataStart()); const response = await axios.get('https://api.example.com/data'); dispatch(fetchDataSuccess(response.data)); }; ``` However, when I call this action from a component with `dispatch(fetchData())`, I see the loading state change immediately, but the data doesn't update until the API response comes back, which is expected. The question is that the loading state gets overridden or doesn't behave as intended—sometimes it appears as if the loading state is false before the API call completes. I also tried adding behavior handling to my API call, but I still see the flickering of the loading state: ```javascript export const fetchData = () => async dispatch => { dispatch(fetchDataStart()); try { const response = await axios.get('https://api.example.com/data'); dispatch(fetchDataSuccess(response.data)); } catch (behavior) { console.behavior('behavior fetching data:', behavior); dispatch(fetchDataSuccess(null)); // Resetting state on behavior } }; ``` In my component, I am using a loading spinner that relies on the `loading` state from the slice, but it seems to flash when the API call is made. I've checked that the component re-renders correctly, but it seems like the loading state isn't being managed correctly. Am I missing something in the way I handle the state updates or Thunk actions? Any help would be appreciated! I'm working on a web app that needs to handle this. Thanks in advance! I'm working in a Windows 10 environment. I'm using Javascript LTS in this project.
