/genie whoisoncall - why is the ordering non-deterministic (or missing rotation labels)

[Kevin Durdle]

Recently ran into an unexpected source of confusion with the opsgenie slackbot.  Specifically, querying whoisoncall returns the participants in a non-deterministic order, and without the rotation label. 

Our setup is fairly simple.  We have a single organization, with a single oncall schedule, that includes two rotations (Primary, Secondary).  

I see the following via slack, where engineer-1 is primary, and engineer-2 is secondary. This is good. 

/genie whoisoncall
Only visible to you #(me)
Oncall Schedules:
my_organization_schedule Participants: engineer-1, engineer-2

However, a peer of mine has observed the following

/genie whoisoncall
Only visible to you #(peer)
Oncall Schedules:
my_organization_schedule Participants: engineer-2, engineer-1

This feels incorrect - either they should be ordered based on rotation ordering, OR, the name of the rotation should be included as follows:

Oncall Schedules:
my_organization_schedule Participants: Secondary: engineer-2, Primary: engineer-1

Question: Has anyone else observed this behavior, or found a solution?

Hi Kevin,

Experiencing a similar issue with a schedule with 2 rotations and a phone integration, OpsGenie appears to be picking randomly between the 2 rotations in the schedule to call first.

We thought it may have been alphabetical, but ruled that out by editing one of the users names.

Wondering the same, if anyone else has a solution
