Queue v1 jobs and sync actions failing, Queue V2 jobs delayed in all stacks

Today since 12:00 UTC we suffer jobs as well as sync actions failing to start due to bug introduced in the last deploy. We are now reverting to the previous working version. 

Update 13:15 UTC (resolved) : We have successfully reverted backend to the previous working version and platform is back operational now.

Update 13:30 UTC: Upon further investigation and damage analysis, we found that Queue v2 jobs were delayed in starting because of this incident. That could result in delays of up to one hour.
