In the Dotnet API project, recently we are upgradign .NET version from 6 to 8.
In the new version of the application, in the nswag.json file
"documentGenerator" engine is changed from "webApiToOpenApi" to "aspNetCoreToOpenApi".
Here is my nswag.json file:

But while executing the below command, it starts the application.

<Exec Command="$(NSwagExe_NET60) run NSwag.json /variables:Configuration=$(Configuration),OutDir=$(OutDir),HomeDir="$(HomeDir)" " />

and produce the below log:

Tried to add below paraeters in nswag but still it is starting the application.
"validateEnums": false, "generateEnums": false,

Anything is missing?
