Fix array overflow in Sync Template v3 Flow Action Details

[Copilot]

The flow fails when environments contain many flows with numerous actions, causing the ActualFlowActionDetails array variable to exceed Power Automate's expression evaluation limits (typically manifesting around 5,000+ items during union() and contains() operations).

Changes

Flow modification (AdminSyncTemplatev3FlowActionDetails-*.json):

• Added $top: 100 to limit flows processed per run
• Reduced pagination minimumItemCount from 100,000 to 5,000

The flow now processes flows in batches, leveraging the existing admin_inventorymyflowactiondetails flag to automatically continue processing remaining flows in subsequent runs.

Documentation:

• Added troubleshooting guide with root cause analysis and manual workaround for pre-fix versions
• Updated Core Components README with reference

Example

For an environment with 300 flows averaging 50 actions each:

• Before: 300 × 50 = 15,000 items in array → flow fails
• After: 100 × 50 = 5,000 items per run × 3 runs → completes successfully

Impact

Backward compatible. Environments with >100 flows now require multiple runs to complete full inventory but gain reliability. The flag-based continuation is automatic.
