Failed to load Swagger API definition for a Newly Published .NET Core 6.0 API

I just pushed a .NET Core 6.0 WebAPI to Azure AppService. When I access the location I receive
the following error issued when accessing the default URL at https://visionsuitecore.azurewebsites.net/index.html below:

Message: Failed to load API definition.

Fetch error
Not Found https://visionsuitecore.azurewebsites.net/v1/swagger.json

My API works perfectly using localhost and within my code, the swagger.json should be located at
https://visionsuitecore.azurewebsites.net/swagger/v1/swagger.json. Further, if I access the URL directly
I can view the contents of the swagger.json as expected.

Why is this and how can I fix it? Please Advise.

    When you have the same name of API Endpoints in the same controller then it will give this error.
