How to retrieve specific profile variables from Watson's Dialog service via the watson-developer-cloud library

When retrieving profile variables from Watson's Dialog service, there is a parameter called name which allows you to control which variables are retrieved. If this parameter is blank, all variables that are associated with the specified client_id are returned. Otherwise, only the specified variables in name are returned.

I finally figured out how to specify more than one variable name on a direct GET to the REST API (give them all the same name, like &name=var1&name=var2), but I can't figure out how to do this via the watson-developer-cloud library. It seems that no matter how I specify names in the dialog.getProfile() function call, it always returns all of the variables.

Can someone tell me how to do this? I don't want to fetch them all every time and then search them for the one I want.

Solution

There was a bug in the library that was preventing name from being sent to the service.

Please update the library by doing

npm install watson-developer-cloud

And try with the example below

var params = {
  dialog_id: '<dialog id here>',
  client_id: '<client id here>',
  name: ['var1', 'var2']
};

dialog.getProfile(params, function(err, response){
  console.log(response)
});
