We had this happen in SMT and did the following Navigate to Customization > Scripting > Script Deployments
1. Add Administrator and non-admin role to these script deployments:
customdeploy_ext_mech_emb_endpoints
customdeploy_ext_mech_installer_event
customdeploy_ext_mech_web_service_rest
customdeploy_ns_sc_ext_mech_restlets
customdeploy_ns_sc_ext_mech_services
customdeploy_ns_sc_ext_mech_ui
customdeploy_ns_sc_ext_mech_web_service
1. Click Edit on each of the script deployments
2. In the Audience subtab, add the Administrator and specific eCommerce role that you created
3. Click Save
