Broken workflow status transition to assigned
**Impact of the bug**
Reqmgr2

**Describe the bug**
During the [HG2209](https://github.com/dmwm/WMCore/issues/11225) validation we have faced a problem with moving workflows' status from `assignment-approved` to `assigned`. Here [1] is the error we face. This has been found while working with ACDC workflows. The general workflow transition seems to be somehow working because we  do see workflows passing to `running-open`. All the conditions under which the bug reveals itself are currently investigated. So far the clues we have point to the following [PR](https://github.com/dmwm/WMCore/pull/11181/files). 

This bug needs to be resolved before we deploy the new release in production.   

**How to reproduce it**
Submit a workflow with central services version WMCore v.2.1.2.pre3 and try to create  and move an ACDC workflow from `assignment-approved` to  `assigned`.

**Expected behavior**
The workflow status transition to proceed with no errors. 

**Additional context and error message**
