Getting exception from Newtonsoft.Json in Dyn365 Online (8.2)

  Hi,

  I'm developing an integration plugin that will call an external web service with data and have run into some issues.

  What I'm doing is making a JSON call to the API of the other system and I get a dynamic object back. The assembly is ilmerged withg Newtonsoft.Json and two dlls from the vendor of the target system. This works on a Dyn365 on premise while sandboxed but when I do it on an online 8.2 I get the following error:

  Unexpected exception from plug-in (Execute): AccountIntegration: System.TypeAccessException: Attempt by method 'DynamicClass.CallSite.Target(System.Runtime.CompilerServices.Closure, System.Runtime.CompilerServices.CallSite, System.Object, System.String)' to access type 'Newtonsoft.Json.Linq.JValue+JValueDynamicProxy' failed.

  if (client.CreateCall<string>("Api/Basic/Register/", project, out outstring, out fault, HttpVerbs.POST))
              {
                  pt.Trace("in call");
                  if (!string.IsNullOrEmpty(outstring))
                  {
                      dynamic outp = JArray.Parse(outstring);
                      pt.Trace("jarray.parce...");
                      if (outp.Count != 1)
                          returnObj = false;
                      else
                      {
                          pt.Trace("är det outp[0]?");
                          var objekt = outp[0];
                          if (objekt["ProjectTypeID"] != "ART")
                              error = "Wrong project type chosen";
                          else if (objekt["Customer"] != customerId)
                              error = "Wrong customer on project";
                          else
                              returnObj = true;
                      }
                      pt.Trace("efter allt koll");
  
  
                  }
                  else
                      error = "No project found";
              }

  It's the line "var objekt = outp[0];" that fails in the online version. Is this something that I can make work somehow? I am a bit surprised that something that works sandboxed on prem doesn't work online. (you can disregard the "pt.Trace" which is pure debug logging)
  

  (Can some moderator please move this to the development thred, I missed a click somewhere, sorry about that.)

  Thanks
