Query returns nothing on matrixBlock

Question

I'm a bit confused by the way that Craft now handles Matrix blocks. I've read the documentation a few times and I'm still not sure if I have it.

Here's what I have:

{% set myMatrixBlockQuery = craft.matrixBlocks().ownerId(4).type('block__artists') %}
{% set matrixBlocks = myMatrixBlockQuery.all() %}
{% for block in matrixBlocks %}
  <li>{{ block.id }} / {{ block.artistName }}</li>
{% endfor %}

But all that gets output is:

8 /
9 /
10 /

Where 10 (etc) is the ID of the block. It's not outputting the artistName despite that field existing and having content. Is my query wrong?

I think you need to add the fieldId() param to your query as per https://github.com/craftcms/cms/issues/1789
