Error: Expected hasMany options.async to be a boolean

[MichalBryxi]

• This one will apply past the AbortController issue, but is essentially the same bucket of issue "Not compatible with Ember Data 5.x"
• I just bootstrapped new empress blog and am getting past the issues.
• The one for this ticket after I manually fix the two above goes:

Given that the most "empress-blog" part of the stack trace is:

    at Module.callback (/var/folders/8q/yrjx_8s115q43r8w5qd90_m00000gn/T/broccoli-35824wMc3OLibHAFp/out-342-broccoli_merge_trees/assets/addon-tree-output/empress-blog/models/author.js:16:1)

I would expect following file contents to be problematic:

import Model, { attr, hasMany } from '@ember-data/model';

export default class AuthorModel extends Model {
  @attr() name;
  @attr() image;
  @attr() coverImage;
  @attr() coverMeta;
  @attr() content;
  @attr() html;
  @attr() website;
  @attr() twitter;
  @attr() facebook;
  @attr() location;
  @attr() meta;

  @hasMany('content') posts;
}

So when I go to: node_modules/empress-blog/addon/models and manually edit all the models so that:

-  @hasMany('content') posts;
+  @hasMany('content', { async: false }) posts;

It will get me past this problem. Can be fixed in empress-blog, but is a bit weird as per v5.3 ember-data documentation this is not strictly necessary.

[MichalBryxi]

Hmm so apparently to the discussion on Discord async and inverse values are necessary since v5.0

[MichalBryxi]

Oh wait, latest master seem to have respective patches

[MichalBryxi]

Just to document this: guides-source has a ticket to have explicit attributes for hasMany, etc.
