'Range where in" returning empty array

{{ range $index, $el := (where .meta.Data.Pages ".Params.tags" "in" $.group ) }}

Builds but always returns an empty array.

Context: Inside a partial in index.html called like: {{ partial "project-group" (dict "meta" . "group" "animation") }}

I want to return array of pages that contain a particular tag. I’ve tried various combinations of context to no avail.
