App is not loading content console says error vendorjs


I run ionic cordova platform add android@6.4.0 and when i run my app with android studio:

I can log in well, but when the homespage comes, the data does not load, and in other pages as well. On every page i do a request, the data does not load, and at the exact same moment i tap on those pages, i see something like this(but with different number) in the console of android studio:

“ERROR”, source: file:///android_asset/www/build/vendor.js (any line)

How can i solve this?
