How could I get voters from a poll?

Trying to reverse engineer the Export button to get poll results, but always get a 422 response.

url
'https://forum.example.com/admin/plugins/explorer/queries/-16/run.csv'
params
{'post_id': 82022, 'poll_name': 'poll2'}
headers
{'Api-Key': 'redacted', 'Api-Username': 'discobot'}
requests.post(url, params=params, headers=headers)
422

Query 16 is the built-in poll report. I’ve allowed admins to access this query. @discobot is an admin.

This username and API key work for all other queries. This is my only Data Explorer-based query (which seems like it would be a really powerful tool, BTW).
