I am running perfect with this code for amost 20 hours.
But then there is an error and the monitor stop.

Operating System: Windows 10

Here is the log

Hey @brianjojoray, thanks for reporting this issue! I suspect that the error log you posted is just the last exception and not the root cause of the crash. Are you sure that the stack trace you posted is complete? To know what caused this crash, we need the first (uppermost) exception from the stack trace.

All the log above.Please help

[philippnormann]

Alright! The first error in your stack trace is sqlalchemy.exc.IntegrityError: (sqlite3.IntegrityError) UNIQUE constraint failed: signage_point_events.ts [SQL: INSERT INTO signage_point_events (ts, challenge_hash, signage_point, signage_point_index) VALUES (?, ?, ?, ?)] which is a duplicate of #29 and should be fixed since 0b92e15. So please update to the latest version and tell me in #29 if this resolves the issue for you.

[brianjojoray]

Thanks.
It's already fixed by update to the lastest version.
