My glitch project won't start, shows an error related to 'start.sh' file

Project is owendorse.glitch.me
Whenever i try to start it, I get an error message
/etc/app-types/static/start.sh: line 11: ws: command not found

Browsing other threads I found out that it might be problem with the server.
Is there any way to fix it?

This is actually a bug on our end. Some files were missing on the server your project was running on. It should be working now. Let us know if you see any more problems.
