Describe the bug

When starting Swagger ui on latest 6.6.1 version, getting error:
Message: JsonTypeInfo metadata for type 'System.Boolean' was not provided by TypeInfoResolver of type 'Swashbuckle.AspNetCore.SwaggerUI.SwaggerUIOptionsJsonContext'. If using source generation, ensure that all root types passed to the serializer have been annotated with 'JsonSerializableAttribute', along with any types that might be serialized polymorphically. The unsupported member type is located on type 'System.Object'. Path: $.AdditionalItems.
