cucumberjs - Xolvio/meteor-cucumber: returning result of this.server.call -

i using package xolvio/meteor-cucumber , i'm trying call fixture method , use returned value in step definition:

step:

and fill in sms code "#smscodeverification"

step definition:

this.then(/^i fill in sms code "([^"]*)"$/, function (verificationfield, callback) {       var code = this.server.call('getsmscodeforuser', "+467*******");       console.log("step code: " + code);        this.client         .waitforexist(verificationfield, 4000)         .waitforvisible(verificationfield, 2000)         .setvalue(verificationfield, code)         .call(callback);     }); 

the above code prints:

step code: [object promise]

the server method looks this:

'getsmscodeforuser': function (tel) {       var user = user.findone({ phone: tel }),         password = password.findone({ user: user._id }),         code = parseint(password.code);        return code;     } 

the console log in step definition run before server method finished, , using meteors normal way of getting callback server methods not work, return undefined.

this.server.call('getsmscodeforuser', "+467*******").then(function(resopnse) {      // can use response here  });
