Folks, any thought?

$ node force.js 
/Users/clientX/node_modules/nforce/index.js:905
      opts.oauth.instance_url,
                ^

here the code

var nforce = require('nforce');

var org = nforce.createConnection({
  clientId: 'xxxxx',
  clientSecret: 'xxxxxx',
  redirectUri: 'http://localhost:3000/oauth/_callback',
  apiVersion: 'v36.0',  // optional, defaults to current salesforce API version
  environment: 'production',  // optional, salesforce 'sandbox' or 'production', production default
  mode: 'single' // optional, 'single' or 'multi' user mode, multi default
});
var oauth;
org.authenticate({ username: 'xxxxxx', password: 'xxxxxxx'}, function(err, resp){
  // store the oauth object for this user
  if(!err){ 
    oauth = resp;
    console.log('Cached Token: ' + org.message);
    } else {
        console.log('Error: ' + err.message);
    }
});

org.query({ query: 'SELECT Id FROM Lead LIMIT 1' }, function(err, res) {
  if(err) return console.error(err);
  else return console.log(res.records[0]);
});

Like all API calls, authenticate() is asynchronous. Therefore that callback needs to happen before you call query(). Try moving your query() code inside of the callback for authenticate().

Also, you don't need to create a variable for oauth if you are using single user mode since the oauth credentials are cached inside of the connection object. You can completely omit that.

thanks @kevinohara80, works perfectly.

Having same issue with nforce node module for chatter feeds .

TypeError: Cannot read property 'instance_url' of undefined at Connection.getUrl (/home/ubuntu/workspace/node_modules/nforce/index.js:709:24) at get_feed (/home/ubuntu/workspace/components/chatter/middleware.js:70:19) at canvas_authentication (/home/ubuntu/workspace/components/chatter/middleware.js:82:7) at callbacks (/home/ubuntu/workspace/node_modules/express/lib/router/index.js:164:37) at /home/ubuntu/workspace/components/organization/index.js:47:20 at Query.<anonymous> (/home/ubuntu/workspace/node_modules/mongoose/lib/model.js:4020:16) at /home/ubuntu/workspace/node_modules/kareem/index.js:273:21 at /home/ubuntu/workspace/node_modules/kareem/index.js:131:16 at _combinedTickCallback (internal/process/next_tick.js:73:7) at process._tickCallback (internal/process/next_tick.js:104:9)

By calling this way... Salesforce.getUrl('/services/data/v29.0'+OAuth.community+'/chatter/feeds/news/'+requestContext.userId+'/feed-items?pageSize=10', OAuth, function(err,resp){ if(!err) { sf_data = resp; render_response(); }else{ console.log('***error: ' + err); response.write(err); response.end(); } });

Hi Kevin,

Here is my code snippet through which i am trying to call an apex rest service and i get the error if(callback) callback(null, data); ^

TypeError: callback is not a function

`'use strict'

var nforce = require('nforce'); var query = 'SELECT Id, FirstName, LastName, Email FROM Lead LIMIT 10';

var oauth; var org = nforce.createConnection({ clientId: 'dfgdfgdfgfdgfd.2XjQ89MlDtOeYXx3SGF0VlfkRqjnYWRJUzj3rE54VhYWlfreMFlRODJIMlcWQ', clientSecret: 'dfgdfggdfgfd', redirectUri: 'http://localhost:3000/oauth/_callback', apiVersion: 'v34.0', environment: 'production', mode: 'single', autoRefresh: true });

org.authenticate({ username: 'gdfgdfgdfg', password: 'gddfgdf'}, function(err, resp) { if(err) { console.error('unable to authenticate to sfdc'); } else { oauth = resp;

org.query({ query: query, oauth: oauth }, function(err, resp) {
  //if(err) throw err;
  if(resp.records && resp.records.length) {
    resp.records.forEach(function(rec) {
      console.log('Lead: ' + rec.get('FirstName') + ' ' + rec.get('LastName'));
    });
  }
});

org.apexRest({uri:'/BlockList/', method: 'GET', urlParams: [{key:'keyWord', value:'hi'}]}, oauth, function(err, resp) {
  //console.log(resp);
  if(!err) {
    console.log(resp);
    //res.send(resp);
  }else{
    console.log(err);
    //
    //res.send(err);
  }
});

} }); module.exports = org;`

Not sure what exactly is the issue, could you please suggest.

Thanks in adavance.
