hello friend, when i tried to read data from whether API i came across bellow message on the browser console.
Access to Font error
‘https://codepen.io’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘https://codepen.io’ is therefore not allowed access.
Any one who can help please
