Application Server Error

[Harini080922]

I am experiencing an issue with my application hosted on Heroku at the domain drone.mithronsmart.com. The app is returning a "503 Service Unavailable" error when accessed, and the page is showing an application error message (screenshot attached).

I have tried the following troubleshooting steps:

Ran heroku logs --tail but couldn’t find specific error logs related to this issue.
Verified my Google Sheets API usage and checked the authentication configurations, but the error persists.
Could you please assist in identifying the cause of this issue and help resolve it?

When in doubt, opening a bug report should be accompanied by providing logs, error messages (text, not images), configuration & information about your app that you do have. If you have trouble obtaining meaningful diagnostics there, show (debug) logs emitted when running your application outside of Heroku.
