✅ Adding API Versioning support to swagger ui

Hi, I've followed this guide exactly: https://markgossa.com/2022/05/asp-net-6-api-versioning-swagger.html
I am getting the following error
My code: https://gist.github.com/dukesteen/24aa6788b98fc0a0e6b2e3f109d2d884
The stacktrace: https://gist.github.com/dukesteen/e26ad88da76c2e81ee5aec4c65e0ca7a

it looks like the configure method is being ran multiple times

not sure

if I set a breakpoint on the options.SwaggerDoc(description.GroupName + "x", CreateOpenApiInfo(description)); line, it runs without exceptions for v1 and v2, but then it returns to v1 and throws

        foreach (var description in _apiVersionDescriptionProvider.ApiVersionDescriptions)
        {
            try
            {
                options.SwaggerDoc(description.GroupName, CreateOpenApiInfo(description));
            }
            catch (Exception ex)
            {
                // ignored
            }
        }

This works but feels more like a hack than a solution

Turns out I was calling AddSwagger twice

Closed!
