Collection loop error: "array variable as a string"

[YoBigRube]

I'm looking for help updating a collection loop from a v2 project to v3.

How it's supposed to work: The loop filters collection entries based on taxonomy term. Matching the slug against a specific term. In the example below the slug is "partnerships", so it should only show the 2 collection entries that are using that term.

The problem: It sort of works - ie. its showing entries, but it's not filtering properly (showing entries that aren't using the term), and it's giving an error (see below).

What's the correct way to write this code block for v3?

Thanks in advance!

{{ collection from="client-stories" :taxonomy:services_type="slug" as="entries" sort="order:number" paginate="false" }}

{{ collection from="client-stories" where="services_type::contains:partnerships" as="entries" sort="order:number" paginate="false" }}

Error log: [2023-04-04 15:59:03] local.DEBUG: Cannot render an array variable as a string: {{ services_type }}
