[BUG] Too many pagerduty schedules causes /incident pager command to time out

[ImDevinC]

Describe the bug
We have 16 schedules in PagerDuty, and when we run /incident pager the command times out. In the log I see the following messages

PagerDuty returned 15 schedules
Error: The request to the Slack API failed. (url: https://www.slack.com/api/views.open) The server responded with {'ok': False, 'error': 'expired_trigger_id'}

Version
1.10.1

To Reproduce
Steps to reproduce the behavior:

1. Create 15 schedules in PagerDuty
2. Type /incident pager

Expected behavior
Modal should popup

Environment (please complete the following information):

• Platform: Kubernetes

Additional context
I'm not 100% sure that 15 schedules causes it, could be the number of users per schedule or something else
