Predictive Routing Queue Config API 400 on Multi-Tenant AppFoundry Sync

Looking for some advice on troubleshooting this specific validation failure when synchronizing predictive routing queue configurations across multiple Genesys Cloud organizations via our AppFoundry integration.

  • The application is designed to maintain consistent routing strategies for a global support network, utilizing the routing:write scope to update queue settings programmatically.
  • We are encountering a 400 Bad Request response specifically when attempting to update the predictiveRouting object within the PUT /api/v2/routing/queues/{queueId} endpoint.
  • The error payload consistently returns: {"code":"bad.request","message":"Invalid predictive routing configuration"}.
  • This failure occurs exclusively for organizations where the maxPredictiveSize is set to values exceeding 500, despite the documentation suggesting higher limits are supported for premium tiers.
  • Our integration uses the Genesys Cloud Node.js SDK (v4.52.0) to construct the request body, ensuring all required fields like outboundContact and predictiveRouting are correctly populated.
  • Interestingly, manual updates through the Genesys Cloud UI for the same queue and configuration values succeed without issue, indicating the data is valid but the API rejection is inconsistent with the UI behavior.
  • We have verified that the OAuth tokens possess the correct permissions and that the target queues exist and are active in the respective organizations.
  • The issue is not isolated to a single environment; it affects multiple production tenants in the us-east-1 region.
  • We suspect there might be a hidden validation rule in the API layer that differs from the UI implementation, possibly related to how agentCapacity or maxPredictiveSize interacts with the total licensed agent count in multi-tenant setups.
  • Has anyone encountered similar discrepancies between UI and API behavior for predictive routing configurations?
  • We are looking for any known workarounds or specific field requirements that might be missing from our payload construction.
  • Any insights into whether this is a known SDK serialization issue or an API backend validation bug would be greatly appreciated.
