OneFlow - 4.6 - Sunstone errors

Hi all ,

Regarding OneFlow, in Sunstone interface, I am receiving two error messages:
- Error: service resource not supported
- Error: service_template resource not supported

OneFlow template could not be saved.

I am using now the latest One (4.6.2) - Debian apt version.

The oneflow-server is configured and started .

There is no record regarding mentioned errors In log files
/var/log/one/oneflow.error /var/log/one/oneflow.log

In Suntone log

"GET
