Invalid value for "Query" on Fetching Pages Field

Following query working properly query: site.find("categories").children But when use advanced query like that: categories: label: Categories type: pages options: query query: fetch: site.find("categories").children value: "{{ page.uid }}" text: "{{ page.title }}" I got the Invalid value for “query” Kirby Version 3.2.2 This is about that and why accept only string?
