Error in Fetch with 'no-cors' Mode

In an attempt to resolve a fetch promise with 'no-cors' mode, developers may encounter errors when the server does not grant permission via CORS. Setting the mode to 'no-cors' prevents the browser from triggering CORS errors, instead leading to silent failures.

However, when parsing the empty response as JSON, the error "Unexpected end of input" arises due to the unavailability of the response body in 'no-cors' mode.

Solution

To address this issue, it is recommended to:

1. Avoid Using 'no-cors' Mode: This mode does not allow you to access the response, making it unsuitable for scenarios where you need to process the server's response.
2. Configure CORS Permission on the Server: The server must be configured to grant permission to the requesting origin through CORS headers. This allows the browser to retrieve the response data without triggering any errors.
