Unable to verify trailhead challenge - Lightning Component Skills & Tools -> Learn the Process for Developing Lightning Components
I have successfully completed the trailhead challenge in my Dev org which is as follows:
Create a test harness app and component
Let's get set up for doing development right now. You'll create a test harness Lightning application, and add a simple component to it. Then you'll verify that you can see changes in the component.
Challenge Not yet complete... here's what's wrong:
The 'harnessApp' Lightning App does not contain ''.
I am unable to understand the error. Anyone who received similar kind of error and were able to proceed further, Please help me with this.
Create a test harness app and component
Let's get set up for doing development right now. You'll create a test harness Lightning application, and add a simple component to it. Then you'll verify that you can see changes in the component.
- Create a new Lightning component named myFirstComponent
- Add this static text to the component: I solemnly swear I know JavaScript
- Create a new Lightning application named harnessApp
- Add myFirstComponent to the harness app with this markup: <c:myFirstComponent/>
- Click the Preview button and verify your text is displayed
- Make a change to the static text so it reads: I am proficient in JavaScript
- Click the Preview button again and verify your change is displayed
