Save button not working in some of the cases in agent workspace

[Rosy14]

Hi

I have modified some field in case via agent workspace. after clicking save it is not saving. for some users it is happening for some not. I checked all roles if it is based on role or not. but could not found anything. plz help. it is happening for some of the cases. in other cases saving working.

Save UI Action:

current.update();

// Track number of cases that are updated via CSM Agent Workspace
var csmWorkspaceUAUtil = new sn_csm_workspace.CSMWorkspaceUAUtil();
csmWorkspaceUAUtil.updateCase(current.sys_id);

Script include:
var CSMWorkspaceUAUtil = Class.create();
CSMWorkspaceUAUtil.prototype = {
    initialize: function() {
    },
	
	// Tracks number of cases that are created via CSM Agent Workspace
	createCase: function() {
		this.logCaseAnalytics('create.case', 'create');
	},
	
	// Tracks number of cases that are updated via CSM Agent Workspace
	updateCase: function(caseId) {
		this.logCaseAnalytics('update.case', 'update', caseId);
	},
	
	// Tracks number of "Create Case" clicks on the Interaction form via CSM Agent Workspace
	createCaseClickInteraction: function() {
		this.logCaseAnalytics('createCase.interaction', 'click');
	},
	
	// Tracks number of "Create Knowledge" clicks on the Case form via CSM Agent Workspace
	createKnowledgeClickCase: function() {
		this.logCaseAnalytics('createKnowledge.case', 'click');
	},
	
	logCaseAnalytics: function(eventType, action, caseId) {
		var data = {};
		data["event.type"] = eventType;
		data["action"] = action;
		data["user.id"] = gs.getUserID();
		if(caseId)
			data["case.id"] = caseId + '';
		this.logAnalytics(data);
	},
	
	logAnalytics: function(data) {
		var streamId = sn_csm_workspace.CSMWorkspaceUAConstants.STREAM_ID;
		var obfuscationList = [];
		
		if (sn_uapaf.ScopedAnalyticsFramework.isDisabled() || sn_uapaf.ScopedAnalyticsFramework.isBlocked(streamId)) {
			gs.info("CSMWorkspaceUAUtil: Analytics Framework is disabled or Blocked!!");
			return;
		}
		
		data["app.name"] = sn_csm_workspace.CSMWorkspaceUAConstants.APP_NAME;
		data["metadata.version"] = sn_csm_workspace.CSMWorkspaceUAConstants.METADATA_VERSION;
		
		status = sn_uapaf.ScopedAnalyticsFramework.open(streamId);
		if (status === 0) {
			status = sn_uapaf.ScopedAnalyticsFramework.sendJSON(streamId, obfuscationList, JSON.stringify(data));
			if(status != 0)
				gs.warn('CSMWorkspaceUAUtil: Unable to send analytics for stream:' + streamId + '; status = ' + status);
			status = sn_uapaf.ScopedAnalyticsFramework.close(streamId);
		} else {
			gs.warn('CSMWorkspaceUAUtil: Unable to open Usage Analytics for stream ' + streamId);
		}
	},
