Issue with Node server on Glitch

I was running a slackbot using the botkit attached to glitch, and it was working up until a couple hours ago. Now I end up with this error when the service tries to start. Any ideas on how to fix this?

That error happens when there’s already a server listening on the port. Could there be two servers starting? What’s the project name?

Ah, figured out the source of the problem. Thank you!
