Warning: Target browser must be a string, but is <object>;

[lsiden]

I get this after I installed grunt-cucumber-js and ran "grunt cucumberjs". I tried to run it from the command-line like so and got more info:

$ node_modules/grunt-cucumber/node_modules/cucumber/bin/cucumber.js

Feature: Homepage
  As a user
  I want to visit the homepage
  So that I can access the various features on offer

/home/lsiden/pah/cpportal/node_modules/protractor-cucumber/node_modules/selenium-webdriver/builder.js:408

My step_definitions/steps.js file was taken directly from the example:
var pc = require('protractor-cucumber');

var steps = function() {
  var seleniumAddress = 'http://localhost:4444/wd/hub';
  var options = { browser : 'chrome', timeout : 100000 };
  this.World = pc.world(seleniumAddress, options);

  this.After(function(callback) {
    this.quit(callback);
  });
};

module.exports = steps;

Is there something else you need to update in the README.md?

i ran it with $ cucumber.js homepage.feature in the feature folder

works if you use the PR referenced in:

 Then I should see a "navbar"       # homepage.feature:8
      TypeError: Invalid locator

Hi,

This appears to be the same problem I solved here:
