@mamund
We already know tthat the API URLs for this book were changed to use railway.app instead of herokuapp.com.
I noticed yesterday, Sept, 8, 2024, that the Activity service on railway.app has stopped working.
$ curl https://activity-production.up.railway.app/list
{"status":"error","code":502,"message":"Application failed to respond","request_id":"UubDgHxYRXSbtSoQMwjmOw_1002618245"}
Note that only the Activity service is affected; the Account and Company services are still working as expected.
Can @mamund or someone repair the Activity service, please?
