Hey @steveh Were you able to get your code to work? I’m having the same issue with Microsoft.CSharp.RuntimeBinder.Binder and I was wondering if you got your solution working after manually bringing in Microsoft.Csharp dll? Thanks! ---

Yes it works now. I zipped up the dll and put it in the custom folder on the server and added the appropriate line to the config to deploy it ---

I am tying to call a Function from Custom Code and followed the Help documentation, but I cannot get it to work. The code compiles in the Code Editor. I know the Function is working because I can call it from a Data Directive. This is the error: Exception caught in: Epicor.Ice.Lib.RestClient # Error Detail Description: Cannot perform runtime binding on a null reference This is the Code: ``` string restApiKey = ""; string libraryName = "PartWebService"; string functionName = "PartSearch"; string part = ""; var functionInputParameters = new RestContent( new { part= "xyz" }); MessageBox.Show(this.txtUBIC.Text); var getByIdParameters = new RestContent(new{ part = part}); var restClient = new RestClientBuilder() .SetDefaultApiKey(restApiKey) .UseSession(oTrans.CoreSession) .Build(); var response = restClient.Function.Post(libraryName, functionName, getByIdParameters, published: true); dynamic responseJson = response.GetJsonResult(); if (responseJson != null) { MessageBox.Show("JSON response."); var functionResult = response.GetJsonResult(); DataSet resultDS = Newtonsoft.Json.JsonConvert.DeserializeObject(responseJson["result?"].ToString()); //DataSet resultDS = JObject.Parse(json)["result?"].ToObject(); eugUBICResult = (EpiUltraGrid)csm.GetNativeControlReference("ed79ae21-fe97-4624-b030-2224b4123cea"); eugUBICResult.DataSource = resultDS; eugUBICResult.DataBind(); } else { MessageBox.Show("JSON returned error."); } ``` ---

I have built the rest connection a little differently because we are using SSO but here is what I have done. Presumably you are passing an API Key and not passing it in blank as per your code snippet? ![image](https://www.epiusers.help/uploads/default/original/3X/e/d/ed6f81e2633dbc5570970a52e6cf20a18d47a914.png) ---

var restClient = new RestClientBuilder().SetAppServerUrl(this.oTrans.CoreSession.AppServer).SetCompanyId(this.oTrans.CoreSession.CompanyID).SetDefaultApiKey(ApiKey).SetIsSingleSignOn(true).Build(); ---

I took that code snippet verbatim from the Epicor Help – Calling Functions from Custom Code. I do an Epicor Application Event Log and it is triggering the Function, but something else is wrong. Whether I specify a blank API Key or this one in API Key Maintenance. I still get the error.
