Failed to load resources on inspecting elements on device

Hi, my ionic app worked well in browser,mobile and also able to see console in chrome device inspect. But after noon i could not able to load console data in my device inspector. currently what i get is

> device ready has not fired after 5 seconds.  cordova.js:1223
> Failed to load resource    file:///android_asset/www/build/index.js.map 

could someone help me to fix this, I need to get console statements in my device inspect window.

is there any other way to view console statement when app is loaded to my device
