Our team is configuring PagerDuty schedules, escalation policies and services via the Terraform PagerDuty provider though I’m not sure if that is relevant as far as the issue is concerned. The error, which is not consistently replicable is:
PUT API call to https://api.pagerduty.com/schedules/XXXYYY?overflow=true failed 500 Internal Server Error. Code: 2000, Errors: , Message: An internal error has occurred. PagerDuty administrators have been notified
The error first started to appear when schedules and services created before daylight savings time was in force were amended during when DST was in force (that is the UTC offset increased by an hour) but again not sure if this is related or relevant.
