Proxy is undefined at .meteor/local/build/programs/web.cordova/app/app.js

Hi
I am trying to run my app on android device but it fails.
I checked simple-todo app is running well on the device but
I am not sure what is the problem on my project.
I wrote very small amount of code originated from todo appliection
I think build was success but at run time , the error is happenning now

below is the error message on

meteor run android-device

it must be major problem…

the error code is below, I think meteor css modules generates the code
I am using meteor-css-modules and scss together

},"styles.scss.js":function(require,exports,module){

the app seems loading but only white background is showing and content is not showing.

it works fine on android simulator

Thank you!!!

I wrote wrong answer so I deleted it and post new correct answer

I copy the code in https://github.com/GoogleChrome/proxy-polyfill/blob/master/proxy.min.js and paste it on /client/proxy.js

I don’t know why it works

Anyway, It works.

Is there anyone to let me know how to add browser polyfill correctly?

Thank you!
