@judeosborncanva See this blog article:

It mentions:
Functions are now defined as methods that receive a standard Request and return a standard Response, in line with the Edge Functions API.
It links to this documentation for the standard Request:
https://developer.mozilla.org/en-US/docs/Web/API/Request
If you’re trying to access the JSON then, (as you’ve mentioned), you want:
console.log( await request.json() )
