Angular - find cause of "[$Injector:unpr] Unknown provider: eProvider <- e" when minified

missingeProvider.js

// Just a tip for ppl debugging such issues in 1.2 -
// This is a short snippet I wrote that will print an error to the console with the contents of the guilty (minified) function.
// All you need to do is put a breakpoint before angular bootstraps, paste the snippet in the console and release the debugger.

Object.defineProperty(Function.prototype, '$inject', {
  configurable: true,
  get: function() {
    return this.$injectHooked;
  },
  set: function (arr) {
    if (arr.length && arr[0].length < 3) {
      console.error('missing @ngInject:', this);
    }
    return this.$injectHooked = arr;
  }
});
