Swagger Authorization Header not visible in ASP.NET Core project

Question

I have included the swagger package(Swashbuckle.AspNetCore) for my asp.net core project. The swagger package is of latest 4.0.1 version. I tried to enable the Authorize button in the swagger ui using below code:

// Register the Swagger generator
services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new Info { Title = "Sample API", Description = "Swagger Sample API", Version = "v1" });
    c.AddSecurityDefinition("Bearer", new ApiKeyScheme { In = "header", Description = "Please Enter Authentication Token", Name = "Authorization", Type = "SampleApiKey" });
    c.AddSecurityRequirement(new Dictionary<string, IEnumerable<string>> {
        { "Bearer", Enumerable.Empty<string>() },
    });
});

The button can be visible in the swagger ui but when i clicked the button, it shows below error:

Can anyone point me out what's the problem here?

Your line should be:

c.AddSecurityDefinition("Bearer", new ApiKeyScheme { 
        In = "header",
        Description = "Please Enter Authentication Token",
        Name = "Authorization", Type = "apiKey"
});

as Type is being transformed inside Swashbuckle as strategy pattern. Possible values are:

basic
apiKey
oauth2

Possibly you can file a bug inside Swashbuckle repo, cos unless it can be overriden it could be for instance an enum, to not bring confusion.
