I have the exact same problem. I have a Net6 Web Api project with swagger client configured. I have no claims

I have AddJwtBearer with this settings

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options =>
{
options.Authority = fusionAuthAuthority;
options.Audience = fusionAuthAudience;
options.RequireHttpsMetadata = false; // DEV only!!
});

and swagger client configured this way

services.AddSwaggerGen(c =>
{
c.AddSecurityDefinition("oauth2", new OpenApiSecurityScheme
{
Type = SecuritySchemeType.OAuth2,
Flows = new OpenApiOAuthFlows
{
AuthorizationCode = new OpenApiOAuthFlow
{
AuthorizationUrl = new Uri($"{fusionAuthAuthority}oauth2/authorize?audience={fusionAuthAudience}", UriKind.Absolute),
TokenUrl = new Uri($"{fusionAuthAuthority}oauth2/token", UriKind.Absolute),
Scopes = new Dictionary<string, string>() { }

         }
     }
 });

 c.AddSecurityRequirement(new OpenApiSecurityRequirement
 {
     {
         new OpenApiSecurityScheme
         {
             Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "oauth2" }
         },
         Array.Empty<string>()
     }
 });

 c.ExampleFilters();

 c.DocumentFilter<OrderTagsDocumentFilter>();

});

Any updates on this issue or hints ?

Thanks
Manlio
