running test cases behind a proxy

I cloned this repo and did the following steps

npm install

npm test (to run the test cases) all test cases launch a blank browser and then timed out. I am guessing this is because I am behind a proxy. I see the following error in all tests

× Before # features\support\hooks.js:46
   Error: function timed out, ensure the promise resolves within 20000 milliseconds
       at Timeout._onTimeout (C:\Users\A418097\Desktop\TestCafe\github\testCafeBDD\testcafe-cucumber\node_modules\cucumber\src\user_code_runner.js:61:18)
       at ontimeout (timers.js:482:11)
       at tryOnTimeout (timers.js:317:5)
       at Timer.listOnTimeout (timers.js:277:5)

and then this error as well

 × After # features\support\hooks.js:60
       ReferenceError: testController is not defined
           at Object.exports.addErrorToController (C:\Users\A418097\Desktop\TestCafe\github\testCafeBDD\testcafe-cucumber\features\support\errorHandling.js:5:5)

I am able to run testCafe cases without cucumber and I do that by adding this line to my package.json

 "scripts": {
    "test": "testcafe chrome Tests/ -e --proxy https.proxy.domain.com:8000"
  },

I am guessing this is the problem why the tests timeout. Could someone point me in the right direction.
