Page-Set-Messages error is not displayed in harness



Messages set at page-level (work object) in the flow action post-activity are not displayed in the harness.

Error Messages

No errors anywhere - nothing in logs, nothing in screen, nothing in tracer.

Steps to Reproduce

There were two distinct issues raised in SR:

Issue 1:
Create a flow action and assign to one step of a screen flow.

Issue 2:

  • Create application

  • Confirm selection with Enter key,
  • Enter Text in “Please describe your request”
  • Do not choose any option in the checkboxes (this will cause the error),

  • The Next Button Disappear:
