Bot Analytics API 422 During BYOC Failover

Looking for some advice on troubleshooting this 422 Unprocessable Entity error from the /v2/analytics/bots/details endpoint. This occurs exclusively when traffic routes through secondary BYOC trunks in Asia/Singapore. The primary carriers return valid JSON with sdk:v2.1. Failover triggers a schema mismatch in the conversation_id field. Is this a known region-specific latency issue affecting payload validation?
