Could not find module `apollo-link-context`

This issue seems to be similar to #137 but that was closed, seemingly without any fix or update. I was having lots of trouble getting ember-apollo-client to work in my actual application. Our Ember version is a bit out of date, so I created a new project just to get this running, so i can rule out version conflicts.

I’m trying to add some headers to my requests, but it doesn’t seem to know how to load apollo-link-context. I see it in my node_modules, but am not sure what the problem is.

import { computed } from "@ember/object";
import ApolloService from "ember-apollo-client/services/apollo";
import { setContext } from "apollo-link-context";

export default ApolloService.extend({

  link: computed(function() {
    let httpLink = this._super(...arguments);

    let authLink = setContext((request, context) => {
      return this._runAuthorize(request, context);
    });
    return authLink.concat(httpLink);
  }),

  _runAuthorize() {
    let headers = {};
    headers['x-user-id'] = '100';
    headers['x-user-uuid'] = 'jahhalhahoyhhalh';
    return headers;
  }
});

the error i’m seeing looks like:

Hello @marsh73 and @sumeetattree!

If you are loading apollo-link-context from your app, you must add it as a direct dependency.

For example:

You are overwriting the apollo service in your app (or engine). If in that file you are importing apollo-link-context or any other dependency, you need to add them to your devDependencies as well ember-auto-import. If you are in an engine, I believe you need to add it to dependencies.

Let me know if that solved your problem.

I don’t think you need to inject the apollo service when using the mixin.
