javascript - 'Path must be a string' error after execute a cucumber feature -

i'm working in implementation of cucumber protractor have conf.js file:

exports.config = {   seleniumaddress: 'http://127.0.0.1:4444/wd/hub',   framework: 'custom',   frameworkpath: require.resolve('protractor-cucumber-framework'),    capabilities: {     'browsername': 'firefox'   },    specs: './features/login.feature',    onprepare: function(){     browser.driver.manage().window().maximize()     browser.get('http:www.google.com')   },    jasminenodeopts: {     showcolors: true, // use colors in command line report.   },    cucumberopts: {     require: 'features/steps/my_steps.js',   } }; 

this step file contain console.log:

module.exports = function(){   this.given(/display something/, function () {     console.log('hi');   }); } 

and feature:

feature: running cucumber protractor    scenario: protractor , cucumber test     given display 

but every time execute command

protractor conf.js 

i'm getting error:

unhandled rejection verror: handler errored, process exiting: prettyformatter::handlefeaturesresult: path must string. received undefined 

i'm not sure if have problems in conf.js or command not right execute.

i hope can me.

this works me:

in conf.js in cucumberopts: add this:

  cucumberopts: {     require: 'features/steps/my_steps.js',     format: 'pretty',     tags:'false'   } 

so me working hope solution guys.
