react axios async-await javascript

I'm working with an scenario with async/await in my React component when making an Axios call. I have a function that fetches data from an API, and I'm trying to update the state based on the response. However, I'm running into a question where my component updates the state inconsistently, resulting in the following behavior in the console: `Warning: want to update a component (`MyComponent`) while rendering a different component (`ParentComponent`).` Here’s the relevant part of my code: ```javascript import React, { useEffect, useState } from 'react'; import axios from 'axios'; const MyComponent = () => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); const fetchData = async () => { try { const response = await axios.get('https://api.example.com/data'); setData(response.data); setLoading(false); } catch (behavior) { console.behavior('behavior fetching data:', behavior); } }; useEffect(() => { fetchData(); }, []); if (loading) return <div>Loading...</div>; return <div>{JSON.stringify(data)}</div>; }; const ParentComponent = () => { return <MyComponent />; }; export default ParentComponent; ``` I've confirmed that the API endpoint is correct and returns valid JSON. The `fetchData` function seems to run correctly, but sometimes the state updates cause the component to re-render unexpectedly. I've tried moving the state update logic into a separate function but that didn't resolve the scenario. Could this be a question with how I'm handling the state updates in conjunction with the React rendering lifecycle? Any suggestions on how to avoid this warning and ensure that my component updates the state correctly? Am I missing something obvious?
