Incorrect content-type sent with latest version of ember-data (3.9.0)

[KroneckerDeIta]

ember-data-hal-9000 version: 0.3.3
ember-data version: 3.9.0

With ember-data version 3.8.0 the correct content-type is sent with a POST request, in particular application/hal+json, however, upgrading ember-data to 3.9.0 causes the content-type to be application/vnd.api+json.

We set the headers ourselves in the HalAdapter by doing

It looks like the ember-data guys have made a change so that the ajaxOptions method now sets the contentType to be application/vnd.api+json.

The workaround in my own code for this is to override ajaxOptions in each of my adapters to be:

/** * Overrides the AJAX options. */ ajaxOptions() { const hash = this._super(...arguments); hash.headers['content-type'] = "application/hal+json"; hash.headers['Accept'] = "application/hal+json"; return hash; },
