FOUR-25052: 422 when creating Non-PO Invoice Approval from Guided Template

[eiresendez]

Issue & Reproduction Steps

The Guided Template script "IDA Helper - Find or Create GL Collection" was failing with 422 Unprocessable Entity when creating GL screens in some tenants.

Root Cause

• The script had screen_category_id = 1 hardcoded.
• In some environments/tenants, category id=1 is System (or category IDs differ). Since system screens are hidden by default, the script did not find existing screens and tried to create them again.

That duplicate create hit screen title uniqueness and returned 422.

Reproduction

1. Use a tenant where screen category IDs differ (or where id=1 maps to System).
2. Start Guided Template: Non-PO Invoice Approval.
3. Flow reaches script task "Find or create GL Code Collection".
4. Observe failure:
5. POST /api/1.0/screens/ -> 422 Unprocessable Entity.

Solution

• Updated script logic to remove hard dependency on screen_category_id=1.
• Added category resolution to select a findable non-system category dynamically.
• Kept the original lookup style (screens/?filter=...).

Result: script no longer fails when category IDs differ across environments.

How to Test

1. In a multitenant/local setup, ensure category IDs are not assumed (e.g., id=1 not guaranteed to be non-system).
2. Run Guided Template Non-PO Invoice Approval.
3. Confirm script task Find or create GL Code Collection completes.
4. Confirm no 422 in tenant logs for POST /api/1.0/screens/.
5. Re-run the same flow to verify no duplicate-create failure.
   6 Validate process continues successfully.
