  Hi OriAssurant

  If your model classes have circular references (e.g., a property in Class A references Class B, and Class B references Class A), NSwag may struggle to generate the schema. Try using [JsonIgnore] or [SwaggerIgnore] attributes on properties that create circular references.

  Thank you oguzhanagir-

  Any other causes you have seen for this issue? After checking for circular references, commenting out many of our custom classes, etc. the issue is still occurring.

  Asp.net Zero dropped the use of Newtonsoft in favor of System.Text.Json in v13 right? Seeing Newtonsoft.Json in the error we're getting.

  Any other ideas of what to check would be very much appreciated. Thanks

  Hi @OriAssurant,

  Can you update the following code on your service.config.nswag

    "codeGenerators": {
      "openApiToCSharpClient": {
        "jsonLibrary": "SystemTextJson", // change this line
      }

  Unfortunately changing "jsonLibrary": "SystemTextJson" in service.config.nswag didn't resolve the issue. Now I can see new errors

  Hi @OriAssurant

  We have found the reason of the problem. It is because of JToken and JObject usages in CustomersController, ExternalController and OrdersController.

  You can either use DTO classes instead or exclude these controllers from swagger as shown below;

  options.DocInclusionPredicate((docName, description) =>
  {
  	var excludedControllers = new[]
  	{
  		"CustomersController",
  		"ExternalController",
  		"OrdersController", 
  	};
  	
  	foreach (var excludedController in excludedControllers)
  	{
  		if (description.ActionDescriptor.DisplayName.Contains(excludedController))
  		{
  			return false;
  		}
  	}
  
  	return true;
  });
