Fix race condition in SYNC HELPER - Get Security Role Users flow

[Copilot]

Problem

AppendToArrayVariable operations fail intermittently when multiple parallel loop iterations write to the same array variable. Power Automate variables are not thread-safe.

Changes

Flow modification:

• Reduced concurrency from 50 to 1 in three loops that append to ActualSrMembers array:
  • Apply_to_each_Direct_Access
  • Add_each_user_no_sub_groups
  • Add_each_user_in_group

"runtimeConfiguration": {
  "concurrency": {
-   "repetitions": 50
+   "repetitions": 1
  }
}

Documentation:

• Added issue response template with resolution steps
• Added troubleshooting guide with technical analysis and manual fix instructions

Impact

• Eliminates intermittent ActionFailed errors in security role sync
• Minimal performance impact: append operations are sub-millisecond, API calls remain the bottleneck
• Sequential processing ensures reliability over marginal speed gains
