ServiceNow REST API: 403 “Forbidden” when accessing sys_script table using custom role (works with admin)

I’m trying to access the sys_script table through the ServiceNow Table API using a custom role, but I always get:

HTTP 403 Forbidden

Field(s) present in the query do not have permission to be read

The same API call works when I use an admin account.

What I’m doing

GET /api/now/table/sys_script?sysparm_limit=1

Custom role:

• x_myrole (example name)

What I have already configured:

1. Added the custom role to my test user.

2. Created read ACL for:

   • Table: sys_script

   • Operation: read

   • Condition: none

   • Requires role: x_myrole

3. No script condition on the ACL.

4. Confirmed that the ACL is evaluated and allowed (checked in debug logs).

5. Also tested with:

   • Full CRUD ACLs

   • Elevated privileges (still fails without admin)

But I still get the same 403 Forbidden response.

What I noticed

• Works perfectly when using a user with admin role.

• Fails only for non-admin users, even though ACLs allow table access.

• This almost looks like there is a system-level protection on sys_script table that prohibits REST access.

Question

Is it possible to access the sys_script table using the REST Table API with a non-admin user?
If yes, what additional ACLs or roles are required to allow REST API access to sys_script?

What I’m looking for

• Confirmation on whether the sys_script table is intentionally restricted from REST API access for non-admin users.

• Whether there are any hidden ACLs, cross-scope protections, or system properties that block access to script tables (like sys_script) through the Table API.

• Clarification on any specific roles (other than admin) that are required to allow REST access to sys_script.

• A way to make this work for a non-admin user, if possible.
