In my case it was wrong configuration in Startup.

code in ConfigureServices was

csharp services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new OpenApiInfo { Version = "v1" }); var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml"; var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile); c.IncludeXmlComments(xmlPath); }

and code in Configure method was

csharp app.UseSwaggerUI(c => { c.SwaggerEndpoint("/swagger/v2/swagger.json", "v2"); });

Problem was: I made middleware with root swagger/v2 json, but defined swagger/v1 above.
Maybe you do the same?
