Protractor stacktrace does not mention the line number on the .js file where the syntax issue or error occurs - protractor

Question

This is my conf.js
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['C:\\Users\\meiyer\\Desktop\\Protractor_Tests\\specs\\specs.js'],
baseUrl: 'https://devcp.us.sunpowermonitor.com/#/dashboard',
// Framework to use. Jasmine is recommended.
framework: 'jasmine',
//Options to be passed to Jasmine-node.
jasmineNodeOpts: {
onComplete: null,
isVerbose: true,
showColors: true,
includeStackTrace: true
}
};
This is my specs.js
var elhLoginpage = {
nameInput : element(by.model('user.UserName')),
passInput : element(by.model('model')),
submitButton :element(by.buttonText('sign in')),
setEmail: function(email) {
this.nameInput.sendKeys(email);
},
setPass: function(password) {
this.passInput.sendKeys(password);
},
clickSubmit:function(){
this.submitButton.click();
}
};
var elhHomepage = {
greetingText : element(by.css('.greeting-des')),
getgreetingText: function() {
this.greetingText.text();
}
};
describe('elhLoginpage login test', function() {
it('should land on homepage when valid username and password is entered',
function(){
elhLoginpage.setEmail('lease_id#test.com');
elhLoginpage.setPass('sun');
elhLoginpage.clickSubmit();
expect(elhHomepage.getgreetingText().toEqual('Hello lease');
});
});
I am executing the test on node.js command prompt as -> protractor conf.js. I am getting below stack trace. From the information below -I am not able to debug on which line number on either of the .js files the issue has occurred. Is there a way to activate this information on stacktrace?

Answer 1

Unforunately that can be a common error in protractor for syntax issues. It's hard to tell without code indentation, but the error is about a missing ) and at a quick glance it looks like you are missing one in your final expect statement.
You have:
expect(elhHomepage.getgreetingText().toEqual('Hello lease');
It should be:
expect(elhHomepage.getgreetingText()).toEqual('Hello lease');
You can use linters like ES Lint to quickly find syntax errors like this.
