Solution 1:

You need to ensure that in your Script Deployment record the Status field is set to Released, and in the Audience sublist, the Employees and/or Roles you want to make the Restlet available to are selected.

Solution 2:

Based on the error, the issue appears to be the Suitelet being called by the RESTlet and not the RESTlet itself. Make sure that the deployment of the Suitelet being called is released as @michoel said.

Solution 3:

Make a copy of the deployment ensuring the Audience, Roles and Released Status are kept and try accessing the RESTlet from the new deployment.

I have experienced issues like the one you mentioned, I suspect Netsuite caches the permissions.
