Hi,

After looking your screenshots ,SOAP Request is missing Target KeyValuePair.

Please find below code for execute action using JS.

var requestXML = ""
requestXML += "<s:Envelope xmlns:s=\"schemas.xmlsoap.org/.../envelope\">";
requestXML += " <s:Body>";
requestXML += " <Execute xmlns=\"schemas.microsoft.com/.../Services\" xmlns:i=\"www.w3.org/.../XMLSchema-instance\">";
requestXML += " <request xmlns:a=\"schemas.microsoft.com/.../Contracts\">";
requestXML += " <a:Parameters xmlns:b=\"schemas.datacontract.org/.../System.Collections.Generic\">";
requestXML += " <a:KeyValuePairOfstringanyType>";
requestXML += " <b:key>Target</b:key>";
requestXML += " <b:value i:type=\"a:EntityReference\">";
requestXML += " <a:Id>" + EntityGuid + "</a:Id>";
requestXML += " <a:LogicalName>" + EntityName + "</a:LogicalName>";
requestXML += " <a:Name i:nil=\"true\" />";
requestXML += " </b:value>";
requestXML += " </a:KeyValuePairOfstringanyType>";
requestXML += " </a:Parameters>";
requestXML += " <a:RequestId i:nil=\"true\" />";
requestXML += " <a:RequestName>" + RequestName + "</a:RequestName>";
requestXML += " </request>";
requestXML += " </Execute>";
requestXML += " </s:Body>";
requestXML += "</s:Envelope>";
var req = new XMLHttpRequest();
req.open("POST", GetClientUrl(), false)
req.setRequestHeader("Accept", "application/xml, text/xml, */*");
req.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
req.setRequestHeader("SOAPAction", "schemas.microsoft.com/.../Execute");
req.send(requestXML);
if (req.status == 200) {
var response = req.responseXML.xml;
}

Hope it'll help you.

Thanks

RE: internal server error (status code:500) while calling an ACTION using SOAP envelope.

There is a much easier way to call actions from javasript

var organizationUrl = Xrm.Page.context.getClientUrl();
                    var data = {

                        "Assign": true,
                        "RemoveFromQueue": true,
                        "TargetItemObjectTypeCode": "112"
                    };

                    var query = "queues(" + queueid + ")/Microsoft.Dynamics.CRM.new_GetNextCaseFromQueue";
                    var req = new XMLHttpRequest();
                    req.open("POST", organizationUrl + "/api/data/v8.0/" + query, true);
                    req.setRequestHeader("Accept", "application/json");
                    req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
                    req.setRequestHeader("OData-MaxVersion", "4.0");
                    req.setRequestHeader("OData-Version", "4.0");
                    req.onreadystatechange = function () {
                        if (this.readyState == 4) {
                            req.onreadystatechange = null;
                            if (this.status == 200) {
                                var caseId = JSON.parse(this.response).ItemId;
                    // do stuff
                            } else {
                                var error = JSON.parse(this.response).error;
                                alert(error.message);
                            }
                        }
                    };

                    req.send(window.JSON.stringify(data));

yes Aman, you are right, actually i guess we can only pass entity reference and can't pass an entity through an action and the code i was trying to execute had and required an entity as i had to perform a change on one of it's attributes but i was casting an entity reference to an entity that's why invalid cast exception occured. so later i changed the code and cast it to entity reference and then retrieved it's attributes in a entity using entity reference's id,columns and logical name. and it worked.

thanks a lot for your guidance and support.

looking forward for further association over the community platform.
