To resolve runtime errors while including AngularJs library in the owa generator

After selecting the "AngularJs" library in the OWA generator, it successfully creates / generates all the required files needed to build a webapp (scaffolding) in the particular directory. It also doesn't show any building or deploying errors. But at the time of selecting the particular webapp from the owa module (in the openmrs running instance), it gives a blank page showing errors in the console window. These errors are to be removed.
