Action Assignment Client Script editor is read-only

[duydv]

Hi team,

I am currently creating a new Action Assignment record in ServiceNow, but I've encountered an issue where the Client Script field is locked. It displays the error message: "Cannot edit in read-only editor."

Thanks!

Hi @duydv ,

Verify if the snc_required_script_writer_permission role is assigned for you, as starting from the Zurich release, even admins require this role to write or modify scripts.

If not assign that role to you and try after logout and login

If my response helped, mark it as helpful and accept the solution

In the Zurich release, ServiceNow enforces a deny‑by‑default model: only users with the snc_required_script_writer_permission role can edit scriptable fields such as Business Rules, Client Scripts, Script Includes, and UI Actions.

Steps

-> elevate your role and add that role to your profile, logout and login again

Thanks, @Ankur Bawiskar and @Dinesh Chilaka 

However, I don't see the snc_required_script_writer_permission role in the role list.
