Could someone clarify why the Genesys Cloud Platform API is returning a 500 Internal Server Error when our AppFoundry Premium App attempts to bulk-create custom objects via a Data Action? The integration is designed to sync external CRM records into Genesys Cloud custom objects for over 200 tenant organizations. The issue manifests specifically when the payload exceeds 50 records in a single POST request to /api/v2/automation/dataactions/customobjects. Smaller batches of 10-20 records succeed without issue, leading us to suspect a server-side processing limit or a specific payload formatting constraint that is not documented in the standard API reference.
The error response body is minimal, providing only a generic 500 Internal Server Error with no detailed stack trace or specific field validation failure. This lack of detail makes debugging significantly more difficult, especially given the multi-org nature of the deployment where we cannot easily replicate the issue in a single development sandbox. The OAuth tokens are valid, and the service account has the necessary customobject:write permissions. We have verified the schema definitions match the expected format for the target custom object, including all required fields and correct data types.
Here is what we have attempted so far:
- Reduced the batch size to 25 records per request, which temporarily resolved the 500 errors but introduced performance bottlenecks unacceptable for our real-time sync requirements. We also added exponential backoff logic to handle potential transient failures, but the errors persist consistently with larger payloads.
- Validated the JSON payload against the Genesys Cloud custom object schema using an external JSON schema validator and compared it against successful smaller batch requests. No structural differences were found, and all field values comply with the defined constraints. We also checked for any special characters or encoding issues in the string fields.
The application is built using the Genesys Cloud Java SDK version 12.3.0, and the backend service runs on AWS Lambda with Node.js 18.x for the initial payload construction before calling the Genesys API via HTTP requests. The environment is set to mypurecloud.com. Any insights into potential hidden limits or known issues with bulk custom object operations in Premium Apps would be greatly appreciated. We are currently evaluating whether to implement a client-side chunking strategy as a workaround, but we prefer a solution that aligns with best practices for high-volume data synchronization.
