Microsoft.Azure.WebJobs.Extensions.OpenApi: OpenApiSecurityAttribute not generating bearer authentication in swagger.json

[snerte]

Describe the issue I am using Microsoft.Azure.WebJobs.Extensions.OpenApi in my azure function to generate my OpenAPI spec. Unfortunately generating bearer token authentication in the swagger.json fails.

Azure function info:

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  </PropertyGroup>

<ItemGroup>
	<PackageReference Include="Microsoft.Azure.WebJobs.Extensions.OpenApi" Version="1.3.0" />
  </ItemGroup>

To Reproduce Steps to reproduce the behavior:

1. Add the OpenApiSecurityAttribute to the function

        [OpenApiSecurity("bearer_auth", SecuritySchemeType.Http, Scheme = OpenApiSecuritySchemeType.Bearer, BearerFormat = "JWT")]

2. Start the function
3. Open the swagger ui
4. Click authenticate

Expected behavior Authentication works in swagger ui, swagger.json securityDefinitions/bearer_auth is generated.

Actual behavior

Error is shown:

On investigation the swagger.json securityDefinitions/bearer_auth is empty:

{
  "securityDefinitions": {
    "bearer_auth": {}
  }
}

Try to set settings for your IOpenApiConfigurationOptions OpenApiVersion = OpenApiVersionType.V3
