500 on PUT /v2/workers/{worker_id} with team set to empty string

[bosconian-dynamics]

It seems like unsetting a worker's team is presently impossible on the v2 API:

• tinybots.net/artbot sends a payload with "team": null which fails type validation for the parameter.
• artbot.site (v2) sends an empty string as suggested in the endpoint doc, but the server responds with HTTP 500 (briefly alluded to in feat: implement worker management artbot#56)

Both ArtBot deployments send the team ID with each Update Single Worker request - so as a side effect, both appear to be unable to update the name/info fields for workers unless a team is selected.

I have confirmed the null/"" responses and inability to update info/name when sending either empty team value in the payload via Postman, as well.
