Duplicate plugin/preset detected.
If you'd like to use two separate instances of a plugin,
they need separate names, e.g.

  plugins: [
    ['some-plugin', {}],
    ['some-plugin', {}, 'some unique name'],
  ]

I believe the issue is this line

ember-cached-decorator-polyfill/index.js

Line 18 in 45ed313

if (!hasPlugin(app, 'ember-cache-decorator-polyfill')) {

not only is it misspelled (missing the d in cached), but looking at how hasPlugin works likely this needs to be the fully resolved path.

    if (!hasPlugin(app, 'ember-cache-decorator-polyfill')) {
