Not working with jsonapi_extras:jsonapi_defaults module

I am using jsonapi_include with jsonapi_default and I can't reproduce this issue.

Steps

1. Go to admin/config/services/jsonapi-include/settings. Confirm "Use jsonapi_include query in URL" setting is OFF.
2. Go to the JSON:API Resource settings page for an entity bundle. (/admin/config/services/jsonapi/resource_types/entity--entity_bundle)
3. To the "Default include list", add the "Alias" for an entity reference field on that entity bundle.
4. Access the "Resource path" shown on that page. There is no need to append any parameters to that URL. The entities specified by alias on the "Default include list" will be included.

@ptmkenny thanks for your quick reply! That's super strange, I played around a lot yesterday and was sure it wasn't working without the URL parameter. Checked it again now and indeed it's perfect.

Sorry for the trouble and thank you once again!
