Protractor fails via jenkins but working on local machine - angularjs

Question

I have a angularjs website. So, i thought of using protractor with jasmine framework for its automation rather than using selenium.
My protractor project which works completely fine on my local machine when i use:
mvn install
My pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</plugins>
</build>
</project>
My conf.js
var Jasmine2HtmlReporter = require('protractor-jasmine2-html-reporter');
exports.config = {
framework: 'jasmine2',
specs: ['./specs/bus_cases.js','./specs/recharge_cases.js'],
baseUrl: 'https://www.mywebsite.com',
capabilities: {
browserName: 'chrome',
shardTestFiles: true,
maxInstances: 2},
},
onPrepare: function() {
jasmine.getEnv().addReporter(
new Jasmine2HtmlReporter({
savePath: 'target/report',
consolidate: true,
consolidateAll: false
})
);
}
};
But when i have deployed the project on github and accessing it thru jenkins, i am getting error:
