FilterBy on autoid doesn't work anymore on structurefield (with autoid plugin)

blueprint

categories:
 label: Categories
 type: structure
 fields:
  autoid: 
   type: hidden
   translate: false                  
  cat_title:
   label: Title
   type: text

site.txt

Categories:
- 
  cat_title: new
  autoid: r8hqec1g
- 
  cat_title: cool
  autoid: 58lfd99u
- 
  cat_title: project
  autoid: 6uewjsbp

The following code doesn’t seem to work anymore on kirby 3.5.
I use the latest autoid-plugin.
$categories= site()->categories()->toStructure()->filterBy('autoid','58lfd99u');
echo count($categories) gives 0;

But following code works on the ‘cat_title’
$categories= site()->categories()->toStructure()->filterBy('cat_title','new');
echo count($categories) gives 1;

Hm, nothing on that side has changed in Kirby.

And when I test your code in a Starterkit (without AutoId installed), I get the expected result.

Indeed, something must be wrong in the autoid plugin.
