Function not running

I keep getting this error in a simple hello world function.

Project Id:
668a841f0014773724f8

Funtion id:
update_location_attendence

Redeploying from cli with 0 changes from previous deployment has solved the issue. But this is the 2nd time the functions stopped working for no reason.

I also have another function with id : "daily_routine" in the same project. It is a Cron based execution which runs daily for months perfectly. But in the last week it has failed 4 out of 7 times with status code 500. With error Function timed out during cold start. Error code 400
