ASP.NET Zero Power Tools - update service-proxies.ts error #6280
Question

I am working on ASP.NET Core & Angular template. After generating the entity via Power Tools, run my *.Web.Host project and then run "./angular/nswag/refresh.bat" to update service-proxies.ts.

The following error is generated even though the server is running...

D:\temp\PhoneBookDemo\angular\nswag>refresh

Checking again I noticed something different on the server. Ask for credentials to authorize....

Any help would be appreciated.
