That points to a specific UI page that ServiceNow uses to handle the impersonation.

If you just remove and readd the single quotes around ‘admin’, the issue goes away.

thx – copying didn’t work but typing did – great script!

It’s probably just a copy/paste issue. I’ve re-added the code to the article above so you can try copying it again and see if that helps. If it doesn’t, then you can simply type the same information directly into the ‘Condition’ field manually to avoid the error.

Is there a way to avoid this error without having the dictionary entry for that field changed?

Thanks for the comment. While that’s possible, it’s also server-side javascript so it does do the impersonation, but it doesn’t automatically refresh the browser so that you know you’re actually impersonating somebody. The other benefit to the client-side solution shown above is that it includes a confirmation prompt so that you don’t automatically impersonate a user by accidentally clicking a button.
