  Hello,

  I have the following code which is triggered when a new connection is created:

              if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
              {
                  // Get the target entity from the input parameters
                  Entity entity = (Entity)context.InputParameters["Target"];
  
                  if (entity.LogicalName == "connection")
                  {
                      // Get the Contact in the From field (record1id)
                      EntityReference fromNameId = (EntityReference)entity.Attributes["record1id"];
                      Guid _contactId = fromNameId.Id;
                      // Get the Connection Role Id (record2roleid)
                      EntityReference connectionRoleId = (EntityReference)entity.Attributes["record2roleid"];
                      Guid _connectionRoleId = connectionRoleId.Id;
  
                      // Use fetchxml to find other active Connection roles with the same id
                      string fetch2 = @"
                          <fetch mapping='logical' distinct='false'>
                            <entity name='connection'>
                              <attribute name='record2id' />
                              <attribute name='record2roleid' />
                              <attribute name='connectionid' />
                              <order attribute='record2id' descending='false' />
                              <filter type='and'>
                                <condition attribute='statecode' operator='eq' value='0' />
                                <condition attribute='record1id' operator='eq' uitype='contact' value='{" + _contactId + @"}' />
                                <condition attribute='record2roleid' operator='eq' uiname='Third Party Authorities' uitype='connectionrole' value='{757A9E2B-B844-E411-80D4-984BE14D9011}' />
                              </filter>
                            </entity>
                          </fetch>";
  
                      EntityCollection result = service.RetrieveMultiple(new FetchExpression(fetch2));
  

  The 'Get the Contact in the From field' works without any issues, but when I try to get the Connection Role (record2roleid) I get the above error.  If the Connection role is coded in the FetchXML it works.  I cannot hard code the value as the plugin will run on different systems and the Connection Role will have different GUIDs.

  Thanks in advance
