When we click Sync button it shows :

JsonError { info: "missing field `media_usn` at line 1 column 115" }

And on AnkiMobile:

Sorry. I found this project "This project is no longer maintained."
I have used Annki's official local synchronization server, Sorry for summit an Issue.

This is confusing so I'll rephrase what OP said:
Use only syncservers that come from the ankitects/anki repo - every other repo (like this one, or the Python anki-sync-server) is not official, and likely fell out of date with whatever the latest versions of AnkiDroid, Anki Desktop and AnkiMobile started doing lately.
