OpenAPI Documents Empty

I upgraded my project to .NET 9, added the OpenAPI services on lines 6 and 16. Then when I go to https://localhost:<port>/openapi/v1.json I get a blank page. The port seems fine since none of the other ports connect to a page, this one does but there's nothing. I don't know what's wrong here. The only thing off I see in my output is 'Middleware: The WebRootPath was not found: C:<project directory>\wwwroot. Static files may be unavailable'
