Why Are AI‑Generated Work Notes Showing Null as the User?

[debendudas]

Hi Community,

I’m configuring an Agentic AI workflow that uses a Dynamic User as the trigger.

When the AI Agent tool updates the work notes on a record, the username is showing as null. Earlier, it used to display “AI”, but now it appears null.

Has anyone faced this issue or found a solution?

Thanks in advance!

Which patch version of ServiceNow are you using, I am having the same issue. Any luck?`
