In your code snippet, the fetchData function is correctly using async/await syntax for handling asynchronous operations. The issue you are facing may be due to the fact that the fetch function itself does not throw an error for network-related issues like failed connections, timeouts, or invalid URLs. Instead, it resolves with an HTTP error status.
To handle these kinds of errors within an async/await function, you need to check the response status of the fetch request and throw an error if it is not within the 200-299 range. Here's an updated version of your code:
async function fetchData() {
try {
const response = await fetch('https://api.example.com/data');
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
const data = await response.json();
return data;
} catch (error) {
console.error('Error:', error);
throw error; // This re-throws the error for the promise chain to catch it
}
}
With this modification, if the fetch request fails for any reason, it will throw an error that can be caught in the catch block of the async function. Additionally, you should re-throw the error in order to propagate it down the promise chain for proper error handling.
Your usage of the fetchData function is correct, and the catch block in the promise chain should now be triggered when errors occur during the fetch operation.
Feel free to test this updated code, and let me know if you encounter any issues or if you have any more questions.
