Hi JYOTI,

Please follow below points:-

You might have multiple Lighting pages with the same name. Go to Setup > Lightning App Builder. You need only 1 Lightning page. Delete all other pages with the same name. Or change the Label of the page.

This error may occur due to some pre-existing configuration that you might have done for other challenges. I would suggest you try in a new trailhead playground.

I request you please post the Trailhead module/project name and what you have tried so that we can look into it and can help you accordingly.

if you need any assistanse, Please let me know!!

Kindly mark my solution as the best answer if it helps you.

Thanks
Mukesh
