Stuck in the trailhead module "Create Secure Lightning Components Module"

For the Challenge1 of 'Create Secure Lightning Components Module', I identified 2 vulnerabilities and removed in the code (as shown in screenshot. However, still I am getting the error "The 'LTNG_Secure_Component_Challenge' component is not yet secured. Remember, unescapedHTML is dangerous. ui:outputRichText is a safer alternative.". I have already replaced unescapedHtml tag with ui:outputRichText. Do anyone come across this?

Try this:
CMP: 
More information: <a href="{!'/'+v.safeCommonMonster}">here</a><BR />
CONTROLLER.JS: 
searchRegionAction : function(component, event, helper) {
        var getRegionAction = component.get("c.getRegionByName");
        getRegionAction.setParams({ regionName : component.find("InputName").get("v.value") });
        getRegionAction.setCallback(this, function(response) {
            var state = response.getState();
            if (component.isValid() && state === "SUCCESS") {
                var region = response.getReturnValue();
                component.set("v.region", region);
                console.log('==region====',region) ;
                //JavaScript: we add a check for only alphanumeric and numeric values 
					var alphaNum = /^[0-9a-zA-Z]+$/; 
                // TODO make this safe 
                if(region.Common_Monster__c.match(alphaNum)) { 
                    component.set('v.safeCommonMonster',region.Common_Monster__c); 
                    } 
               
            }
        });
        $A.enqueueAction(getRegionAction);
	},

This is the whole code which I have used and passed the challenge.

You need to do two changes in the component and one change in the controller.
Component

<!-- TODO make this link work -->
More information: <a href="{!'/'+v.safeCommonMonster}">here</a><BR />

Description: <ui:outputRichText value="{!creature.Description__c}" /> <BR />

Controller:

// TODO make this safe 
 var alphaNum = /^[0-9a-zA-Z]+$/;
 if(region.Common_Monster__c.match(alphaNum)) {
           component.set("v.safeCommonMonster",region.Common_Monster__c);
  }

Hello All,
Need one quick help here. as this challenge can not be completed in standard Developer Edition or Trailhead Playground. We must sign up for a super-special Kingdom Management DE org. I did the signup but not able to Launch KM DE org from trailhead and that is why I am getting "The 'LTNG_Secure_Component_Challenge' component was not found." How did you guys solve the challenge?
Any help would be appreciated.

When taking the c=hallenge Go to manage orgs instead to choosing trailhead playground . Add your Kingdom Management DE org in it.
