Botkit SDK 502 Bad Gateway

I have configured according to docmunent but why not correct ?
Please help me !




I’ve faced the same problem.
Make sure you’re running the app.js file.
And every time you make a change in your other botkit-master js files, stop and re-run the app.js file.

Right now, we have the same issue.

A few weeks ago it was working fine, it seems it could be an issue of Kore server
