I have made using Glitch but it did not submitting. What is the problem here I did not found anything.
Project Link:-https://dull-gram.glitch.me/
Github Project:- https://github.com/avi-jkiapt/timestampMicroservice

Please tell me what is issue in this project.

After adding “cors” file all the testcases have passed. After getting through the link provided to start project i matched with my file and after that i find that “cors” is missing in package.json and then I added it.
