Include categories custom fields in REST api - json

Question

I am working with Advanced custom fields, where I add an image selector for categories in wp - But I can't see the data in my JSON response for categories?
I have tried to use several plugins to do the same, but That haven't worked either -
I am using ACF to rest plugin to include acf fields in the response, which works fine on custom post types - where it creates an array field called "acf"
This field is not created in my categories though - Am i missing a function to use it in taxonomies?
examples.
domain.com/wp-json/wp/v2/recipies (a custom post type)
returns everything including acf.
domain.com/wp-json/v2/categories (a texonomy)
returns all of the categories, but nothing about acf
domain.com/wp-json/wp/v2/categories/37 (a single category)
returns the category but nothing about acf.
domain.com/wp-json/wp/v2/categories/37?_embed[0] (way of getting all embedded stuff)
Does not show acf
Hope that you can put me on the right path.

Answer 1

To anybody who is interested, and runs into this problem.
I talked to the developer of acf-to-rest, and there is a bug in version 2, where it doesn't save taxonomies correctly - It is fixed in version 3, but you can't update it yet through wordpress, since it is still in beta -
Redownload the plugin and go into your wp-config file
here you need to define that you are going to use version 3. paste this line into the wp-config file
define('ACF_TO_REST_API_REQUEST_VERSION', 3);
The endpoints has been rewritten, so you also need to read up on that if you are using the acf endpoints for updating etc.

I hope that this will help somebody in the future.
