3 Console Messages

A page may trigger messages to the console to be logged. These are often error messages about being unable to load a resource or execute a piece of JavaScript. Sometimes they also provide insight into the technology behind a website.

Source	Level	URL Text
network	error	URL: https://learn.aisingapore.org/ Message: Failed to load resource: the server responded with a status of 403 ()
javascript	error	URL: https://learn.aisingapore.org/ Message: Access to fetch at 'https://api.radar.cloudflare.com/api/beacon' from origin 'https://learn.aisingapore.org' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
