Error with Swagger UI with new application service #2304

Hi,

I am using an external API with this project and so have created a new application service to handle the client calls that need to be made to the external API. When running the project and the Swagger UI page opens it is blank with a 500 Internal Server Error on the request in the network tab of browser dev tools.

The code I am using is as follows (areas omitted as it is a private API), the code works in isolation, and also worked on an old version of ASP.NET Zero with ASP.NET MVC and Angular 1.

public async Task<string> GetDocumentPreview(GetDocumentPreviewInput input)
        {
            using (HttpClient client = this.GetClient(input.Token))
            {
                var response = await client.GetAsync(string.Format("api/previews/{0}/page/{1}", input.Id, input.PageNumber));

                //var response = new HttpResponseMessage(System.Net.HttpStatusCode.OK);

                if (response.IsSuccessStatusCode)
                {
                    //Omitted
                }
                else if (response.StatusCode == System.Net.HttpStatusCode.Forbidden)
                {
                    //Omitted
                }
                else
                {
                    //Omitted
                }
            }
        }

        private HttpClient GetClient(string token)
        {
            HttpClient client = new HttpClient();
            client.BaseAddress = new Uri("Omitted");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
            if (token == null)
            {
                throw new UserFriendlyException("Error when authenticating request!", "Authorisation token was null, please sign in again or contact support");
            }
            client.DefaultRequestHeaders.Add("Token", token);

            return client;
        }

I have noticed that if I create a new HttpResponseMessage manually the Swagger UI works fine, but when obtaining the HttpResponseMessage from .NET's HttpClient.GetAsync method the error is occuring.

Can Swagger not handle generating the available API methods if there is an external call with HttpClient? If so is there any way to have the call in place and still have the project run correctly as I cannot run the refresh.bat in the client with Swagger broken.

Any help is appreciated

Thanks

    Hi,

    I haven't tried this scenario before. Have you checked Logs.txt file, there might be extra information about the error.

    Edit: Found the problem, there was a missing reference. I never realised because there were no errors during build
