c# - System.ServiceModel.FaultException - how to solve this

Question

I am standing up an API that connects to a WSDL for an imaging system. I can successfully make the call I am attempting with SoapUI, so there isn't an issue with the WSDL. Before making the call that is throwing this exception I can successfully return the login session token (If I comment out this code I an release the session as well). So I can communicate with the WSDL, just not this call. I don't really understand this exception and online searches have just confused me more.

This is a .NET Core project (C#).

$exception {"Synergy Application Error"} System.ServiceModel.FaultException Action null string

Please help me understand this exception and how to fix it. I have asked the other programmers at work and got an I don't know.

Here is the code that calls the wsdl

    using System;
using System.Threading.Tasks;
using SimnetWebService;
using SynergyApi.Models;

namespace Simnet
{
    public partial class SimnetConnector :ISimnetConnector
    {
        public Task<GetItemBySearchResponse> GetCheckBySearchAsync(CheckSearchDto checkSearchDto, string sessionToken)
        {
            return GetCheckBySearchInteralAsync(checkSearchDto, sessionToken);
        }

        private async Task<GetItemBySearchResponse> GetCheckBySearchInteralAsync(CheckSearchDto checkSearchDto, string sessionToken)
        {
            try
            {
                SynOptionEnums[] synOptionEnums = new SynOptionEnums[1];
                synOptionEnums[0] = 0;
                SynItemRequest synItemRequest = new SynItemRequest()
                {
                    StartPage = CheckSearchOptions.StartPage,
                    NumberOfPages = CheckSearchOptions.NumberOfPages,
                    Extension = string.Empty,
                    Options = synOptionEnums
                };

                GetItemBySearchResponse getItemBySearchResponse =
                    await _service.GetItemBySearchAsync(sessionToken, CheckSearchOptions.CheckSearchName, CheckSearchEnum,
                    checkSearchDto.CheckSearchXML, CheckSearchOptions.SearchTimeout, synItemRequest);

                return getItemBySearchResponse;
            }
            catch (Exception e)
            {
                //TODO: handle exception, log exception
                var ex = e;
                throw;
            }
        }
    }   
}

Answer 1

Ok so I have solved the issue. It was an error in the XML search parameter. The exception was totally not helpful in finding that. Another coworker found where the error was...you know you can't see your own mistakes. Thank you to anyone that attempted to look at this for me.
