Managing Packages with Npm - Package.json should have valid author key error

I am not able to complete this challenge. I have tried cloning the github repo, cloned the glitch repo. Used the app homepage link. But nothing works it shows:

package.json should have a valid “author” key

Is it broken or am I doing something wrong:
Glitch url:
Github url:

The project only have a Readme file and an assets folder.

Use live app link of the glitch, dont directly paste your github link
