In your code snippet, the issue might be that the error handling in the fetchData function itself is not properly catching errors. When using async/await, errors thrown within the async function are converted into rejected promises. However, if the fetch call itself fails, it will still throw errors like network errors, incorrect URL, etc., which need to be handled separately.
Here's an updated version of your code with improved error handling:
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 inside fetchData:', error);
throw error; // Re-throw error to propagate it to the caller
}
}
// Usage
fetchData()
.then((result) => {
console.log('Data:', result);
})
.catch((error) => {
console.error('Error in promise chain:', error);
});
In the updated code:
1. Check for response.ok to ensure that the response is successful. If not, throw a new Error.
2. Catch any errors inside the fetchData function and re-throw them to propagate them to the caller.
This will help in handling errors such as network issues or failed HTTP requests more effectively. If there are other issues with the code or if you encounter specific error messages, please provide more details so we can further assist you.
