Analytics API 404 mapping Zendesk CSAT to Genesys Cloud

Just noticed that the Analytics API returns a 404 when trying to fetch CSAT data mapped from Zendesk tickets to Genesys Cloud interactions.

“Custom attributes are not supported in the base query for digital channels.”

The endpoint /api/v2/analytics/interactions/query seems to ignore the custom attribute filter entirely. Is this a known limitation for Zendesk-to-GC migrations?
