Uncaught TypeError

When running localhost:4200/sightings/new I get this error message:

Uncaught TypeError: _this.get(…) is not a function
at x-option.js:77
at invoke (ember.debug.js:336)

Addtionally there seems to be an internal server issue:

POST https://bnr-tracker-api.herokuapp.com/api/sightings jquery.js:9536
500 (Internal Server Error)

Anybody experience this issue?

The same with me. I don’t what is the problem. I installed ember-cli@2.4 (in package.json it is 2.4.3)
this is my dependencies.

  "devDependencies": {
    "broccoli-asset-rev": "^2.4.2",
    "ember-ajax": "0.7.1",
    "ember-cli": "2.4.3",
    "ember-cli-app-version": "^1.0.0",
    "ember-cli-babel": "^5.1.6",
    "ember-cli-dependency-checker": "^1.2.0",
    "ember-cli-htmlbars": "^1.0.3",
    "ember-cli-htmlbars-inline-precompile": "^0.3.1",
    "ember-cli-inject-live-reload": "^1.4.0",
    "ember-cli-qunit": "^1.4.0",
    "ember-cli-release": "0.2.8",
    "ember-cli-sass": "6.1.1",
    "ember-cli-sri": "^2.1.0",
    "ember-cli-uglify": "^1.2.0",
    "ember-data": "^2.4.2",
    "ember-export-application-global": "^1.0.5",
    "ember-load-initializers": "^0.5.1",
    "ember-resolver": "^2.0.3",
    "emberx-select": "2.0.2",
    "loader.js": "^4.0.1"

i installed emberx-select@3.0.0, then @2.2.3 and now 2.0.2 just like the solutions code, but nothing happens.

I am stuck here too. This is quite frustrating. I am just going to use the emberjs guide tutorial. Starting from scratch elsewhere sigh

Hi @jubalrahl, Ember has definitely seen a lot of change in the 12 months since printing, so it is quite possible one of the dependencies has made a breaking change (x-select definitely broke some things). Which error are you getting? The error from x-select or an error POSTing to the Tracker server?

Here is a thread from errata about switching to the newer x-select, hope it helps! Install EmberX-Select p.437
