Analytics Query API 500 on Custom Report Connector

Pushed the custom reporting module to client staging org using genesys-cloud-sdk-js@3.78.1. The /api/v2/analytics/details endpoint doing jack all. It’s rejecting GET requests with 500 Internal Server Error when filtering by queueId, even though the payload matches the schema perfectly. Console logs show the OAuth token refreshing fine but the analytics service just drops the connection right after the handshake.
