Bot Analytics API returning 401 despite valid Multi-Org OAuth

Quick question, has anyone seen this weird error? with the bot analytics endpoint. Using standard multi-org OAuth token but getting 401 Unauthorized when hitting /api/v2/analytics/botconversations/details/query during load tests.

“Ensure the OAuth token includes the analytics:view scope for accessing detailed conversation metrics.”

Token has the scope, yet it fails consistently after 500 requests. Any ideas on rate limiting or scope validation quirks?
