I am working on SPEAK UI in Sitecore.

I have created the button, Which is named as Edit Meta under content/webedit/ribbons/webedit in core database. This button will be shown in Experience Editor section when I click Edit Meta button. I need to show the Data in a popup window related to that particular Meta section. I gave the command name, script file path, Access Key in button layout properties.

When i click the button in Experience Editor it shows below error.

A serious error occurred please contact the administrator

I un-commented the code which is related to SPEAK ui in sitecoreMvcExperienceEditor.config also. I have added Sitecore.Support.122942.dll also.

I checked the log file and it shows Could not instantiate speak request object. Please suggest how to resolve this issue?

I followed below steps.

  • I logged into core database using Sitecore Rocks.
  • I have created the Item(Meta) using strip template under Content/Applications/Webedit/Ribbons/Webedit/ in core database and given the Header Name and Id .
  • Added strip layout for Meta Item in presentation details.
  • Created the Item Under Meta by using Chunk template, given HeaderName and Added Chunk layout in presentation details.
  • Created another item(EditMeta) under Meta chunk using Largebutton template & given the Header name also.
  • Added the LargeButton rendering for MetaData in presentation details.
  • I have edited the property details of Largebutton rendering. below I mentioned the property details of Largebutton rendering.
  • enter image description here

My Js file.`

define(["sitecore", "/-/speak/v1/ExperienceEditor/ExperienceEditor.js"], function (Sitecore, ExperienceEditor)


Sitecore.Commands.LaunchFieldEditor =
    canExecute: function (context) {
        return true;
    execute: function (context) {

        context.currentContext.argument = context.button.viewModel.$el[0].accessKey;

        ExperienceEditor.PipelinesUtil.generateRequestProcessor("ExperienceEditor.GenerateFieldEditorUrl", function (response) {

            var DialogUrl = response.responseValue.value;
            var dialogFeatures = "dialogHeight: 680px;dialogWidth: 520px;";
            ExperienceEditor.Dialogs.showModalDialog(DialogUrl, '', dialogFeatures, null);



My class:

public class GenerateFieldEditorUrl : PipelineProcessorRequest<ItemContext>

public string GenerateUrl()

    var fieldList = CreateFieldDescriptors(RequestContext.Argument);
    var fieldeditorOption = new FieldEditorOptions(fieldList);
    //Save item when ok button is pressed
    fieldeditorOption.SaveItem = true;
    return fieldeditorOption.ToUrlString().ToString();
private List<FieldDescriptor> CreateFieldDescriptors(string fields)
    var fieldList = new List<FieldDescriptor>();
    var fieldString = new ListString(fields);
    foreach (string field in new ListString(fieldString))
        fieldList.Add(new FieldDescriptor(RequestContext.Item, field));
    return fieldList;
public override PipelineProcessorResponseValue ProcessRequest()
    return new PipelineProcessorResponseValue
        Value = GenerateUrl()

I added the reference in Sitecore.ExperienceEditor.SpeakRequest.config

        <request name="ExperienceEditor.GenerateFieldEditorUrl" type="Website.Modules.Components.ExperienceEditor.FieldEditor.GenerateFieldEditorUrl, Website.Modules" />

Could you please suggest, how to fix this issue?

thanks in advance

    Please open Sitecore logs, see what errors/exceptions happened around that time, and include those error messages as a part of your question. Commented Mar 2, 2017 at 8:05

    I'm voting to close this question because it is incomplete - without enough information to diagnose the issue - and possibly a bit off-topic. It looks like what the author really needs is some help getting through a tutorial/walkthrough, and I would expect that better help could probably be found by asking the question in Sitecore Community Slack Commented Mar 3, 2017 at 18:01

with in Sitecore.ExperienceEditor.Speak.Server.RequestArgs class the method name to execute defaults to Process. Check the last line in below method.

public RequestArgs(string commandPath, NameValueCollection queryString, string data)
   Assert.ArgumentNotNull(queryString, "queryString");
   this.QueryString = queryString;
   this.Data = data;
   string[] array = StringUtil.RemovePrefix('/', StringUtil.RemovePostfix('/', commandPath)).Split(new char[]
   Assert.IsTrue(array.Any<string>(), "Missign request name");
   this.RequestName = array[0];
   this.MethodName = ((array.Length == 1) ? "Process" : array[1]);

Either you have to create your request as ExperienceEditor.GenerateFieldEditorUrl/ProcessRequest

Or change the method below in GenerateFieldEditorUrl class to Process from ProcessRequest

public override PipelineProcessorResponseValue ProcessRequest()

Please look at your log file.

  • There may be many scenarios:

Scenario 1 (I was facing this issue): Social Media is disabled in your configuration file but related items do exist in CORE database.

ERROR: Error processing command url:/-/speak/request/v1/expeditor/ExperienceEditor.Social.SocialCenter.GetMessagesCount error:System.InvalidOperationException: Could not retrieve request class for url:/-/speak/request/v1/expeditor/ExperienceEditor.Social.SocialCenter.GetMessagesCount at Sitecore.ExperienceEditor.Speak.Server.RequestHandler.Process(HttpContext context) at Sitecore.ExperienceEditor.Speak.Server.RequestHandler.ProcessRequest(HttpContext context) Solution: Remove these two items from CORE DB:

Solution: Remove these two items from CORE DB: • /sitecore/content/Applications/WebEdit/Ribbons/WebEdit/Page Editor/Social • /sitecore/content/Applications/Content Editor/Ribbons/Chunks/Social

Scenario 2: URL Rewrite issue with SPEAK request
ERROR Error processing command url:/-/speak/request/v1/expeditor/optimization.activeitemtest error:System.InvalidOperationException: Could not retrieve request class for url:/-/speak/request/v1/expeditor/optimization.activeitemtest

Solution: Well explained in given blog (However, this was not the problem I was facing). https://codeandnuts.wordpress.com/2017/04/19/sitecore-experience-editor-issue-a-serious-error-occurred-please-contact-the-administrator/
