Issues using a repeater field with the REST API

Hey guys, I’ve registered a custom REST field to allow a user to get and update some data in an ACF repeater field.

The issue I’m having – actually there are two – is that the response from the POST request to update the record contains the previous value of the ACF repeater row.

I’ve narrowed this down to two things. Firstly, when I update the record, ACF maintains an $active_loop, which I needed to reset after updating the row, which I have done so using reset_rows(); This was causing the have_rows() loop to return false when I was fetching the new data for the row.

Secondly – and where I’m still stuck- is when I go to fetch the updated record. It seems like ACF maintains a local store of fields, which it queries before it looks at the database acf-value-functions.php line 64 $store = acf_get_store( 'values' );.

I found an undocumented function acf_reset_local() which I thought would clear the store, but it doesn’t work. I need to clear the store (or at least update it), so that I can fetch the correct record from the database.

Any help would be greatly appreciated. Thank you in advance.

public static function get_private_note($prepared, $field_name, $request, $object_type)
    {
        if (have_rows('private_notes', $prepared['id'])) {
            while (have_rows('private_notes', $prepared['id'])) {
                the_row();
                $user_id = absint(get_sub_field('user'));
                if ($user_id === get_current_user_id()) {
                    return get_sub_field('private_note');
                }
            }
        }

        return '';
    }

    public static function update_private_note($value, \WP_POST $object, $field_name, $request, $object_type)
    {
        if (have_rows('private_notes', $object->ID)) {
            while (have_rows('private_notes', $object->ID)) {
                the_row();
                $user_id = absint(get_sub_field('user'));
                if ($user_id === get_current_user_id()) {
                    update_sub_field('private_note', esc_html($value));
                    break;
                }
            }
            reset_rows();
        } else {
            add_row('private_notes', [
                'user' => absint(get_current_user_id()),
                'private_note' => esc_html($value),
            ], $object->ID);
        }
    }
