Server port does not validate enum.

[alsals126]

FIndRoute Does Not Check enum server port. Ports are specified by Server Variable Object, enumeration values that were not declared as default cannot use.

I referred to the example of https://swagger.io/specification/#server-object.

request

https://demo.gigantic-server.com:443/v2 (port 443 is not the specified default value.)

result

no matching operation was found
