update_field not serializing value on relationship field

I am having an issue with using update_field on a relationship field. I have a post that has a user_id relationship field.

When I update the post using update_field, the user id is stored as a string.
update_field(‘field_5d3737638274e’, $user_id, $request_id);

However when I update the post via WP Admin, it saves the user id as a serialized value.

Presumably the serialized value is the correct way. Does anyone have an idea why the function isn’t saving properly when called via custom php?

update_field('field_5d3737638274e', array($user_id), $request_id);

That worked, thank you John!
