To handle a fetch request error when the API returns a non-200 status code and still parse the JSON response, you can check the response status and handle it accordingly. Here's a clean example:

<!-- BEGIN COPY / PASTE -->
        fetch('https://api.example.com/data')
            .then(response => {
                if (!response.ok) {
                    return response.json().then(errorData => {
                        throw new Error(`Error: ${response.status} - ${errorData.message}`);
                    });
                }
                return response.json();
            })
            .then(data => {
                console.log('Data:', data);
            })
            .catch(error => {
                console.error('Fetch error:', error.message);
            });
        <!-- END COPY / PASTE -->

Additional Comment:

The "fetch" function is used to make the request to the API.
The "response.ok" property checks if the status code is in the range 200-299.
If the response is not "ok", the JSON error data is parsed, and an error is thrown with a custom message.
The "catch" block handles any errors, including network issues or the custom error thrown for non-200 status codes.
