HTML type field not saving when Business Rule runs as system user after Wait Rule - Zurich

[NoorulHudaN]

Hi Community,

We have a Business Rule that creates incidents based on incoming alerts from an external monitoring tool. It includes a Wait Rule - when the wait completes, a scheduled workflow runs as the system user and executes a post processing script to populate fields on the incident.

The problem is - the HTML type field on the incident table fails to save when running as system user. String fields work fine.

createdTask.setValue('u_description', '<b>Test</b>'); // ❌ blank
createdTask.setValue('description', 'Test');           // ✅ saves fine

What we confirmed:

• Security debug shows RC = true for incident.u_description/write — so ACLs are not blocking
• Same code works fine when running as service account (without wait rule)
• Issue is specific to Zurich — works fine on older versions
  
  Is there a known platform change in Zurich that affects writing to HTML type fields when running as system user in a background context?

Hi @Ankur Bawiskar 
Thanks for your response.
Just to confirm - does the Scripting Governance restriction on HTML fields also apply to the system user? Given that system runs with the highest privilege and bypasses ACLs..

yes it does apply to that user.
