Ionic build (or emulate) android returns path.js8


I’ve running build and emulate ok (for the most part) and now just added the .ai & .png files in resources and now all build / emulate / run commands are returning…

    throw new TypeError('Path must be a string. Received ' +

Error: Hook failed with error code 1: ...\app\project\hooks\after_prepare\icons_and_splashscreens-org.js

Also I updated lodash hoping that would fix it. No luck.

Any idears?
