getSpecialtiesV2 method does not implemented

[maksgru]

Upwork-API docs says that i can use getSpecialtiesV2() method
https://developers.upwork.com/index.html?lang=node#metadata_list-specialties-v2
But here https://github.com/upwork/node-upwork/blob/master/lib/routers/metadata.js i can't find this method
I tried to use request directly like

metadata.api.client.get('profiles/v2/metadata/specialties', { topic: '1517518458442309632' }, (err, data) => {
    console.log(err, data);
  });

but i got error

"server_time":1657311539,"error":{"status":400,"code":400,"message":"Wrong metadata type specified"
