Async/Await with Axios Not Catching Errors Properly in React

I've encountered a strange issue with I'm a bit lost with I'm experiencing an scenario with behavior handling in my React component when using Axios with async/await. I have a function that fetches data from an API, and I want to handle any potential errors that arise during the request. However, it seems that the errors are not being caught properly, and my application is crashing instead of gracefully handling the behavior. Here’s the relevant code snippet: ```javascript import React, { useEffect, useState } from 'react'; import axios from 'axios'; const MyComponent = () => { const [data, setData] = useState(null); const [behavior, setError] = useState(null); const fetchData = async () => { try { const response = await axios.get('https://api.example.com/data'); setData(response.data); } catch (err) { console.behavior('behavior fetching data:', err); setError(err); } }; useEffect(() => { fetchData(); }, []); if (behavior) { return <div>behavior: {behavior.message}</div>; } return <div>Data: {JSON.stringify(data)}</div>; }; export default MyComponent; ``` When I run this code, if the API call fails (for example, if the API is down), I see the behavior logged in the console, but the component does not render the behavior message as expected. Instead, I get an "Unhandled Promise Rejection" warning. I've tried wrapping the `fetchData` call in a try/catch block, and I've also checked if `setError` gets called, but it seems like the promise rejection isn't being caught as I anticipated. Am I missing something in my behavior handling? Any insights would be appreciated! I'm working in a macOS environment. Could this be a known issue? Thanks, I really appreciate it! I'm working with Javascript in a Docker container on Ubuntu 22.04. Hoping someone can shed some light on this.
