Node project failed to start application and cannot solve error

Hi folks, I’m having errors on my networked-aframe project. I can edit it on Glitch, but when press ‘Show’ it shows : “failed to start application on ilearn-official.glitch.me This is most likely because your project has a code error.Check your project logs, fix the error and try again.”
As a newbie, I’m having a hard time finding and solving the error. Can anyone help? Here’s my glich code:Glitch :・゚✧

I don’t know enough about the libraries being used but you have a lot of interconnected parts any of which could be generating an error. easyrtc for instance is using authorization. And I notice a particular old version of Node being used.

You should scatter console.log lines throughout the startup code to see if there are any clues on where the failure occurs and of course what the issue is.
