You are not allowed to access 'addPrincipalToGroup' in this context

Once a year, I'm updating a Plone 4.2 site dedicated to a meeting. One of the tasks is to move members from some groups to others. For this, I'm using in a Python Script (with Manager Proxy Roles):

context.portal_groups.addPrincipalToGroup(email_member,new_group)

IIRC, this used to work nicely previous years but, now, I'm facing a:

You are not allowed to access 'addPrincipalToGroup' in this context

error. Here is the complete traceback:

Do you know how to fix this error?

Maybe you could enable verbose security to see if it gives you more info: https://docs.plone.org/develop/plone/security/permissions.html#permissions

Good advice: hence, I realized the owner of the script used to be a Manager but isn't anymore.
