I was debugging my app and had no idea what happens, script just didn't execute some lines.
Then I added console.log('step1'), console.log('step2') etc. after each line and found that script stops on certain step and don't output anything. However I added try ... catch block around. After some research I solved it with removing commented line in sync.js.
