Looking for advice on handling a specific validation error during our bulk recording export process. We are integrating Genesys Cloud recordings with our legal discovery workflow using the Quality Management and Recording APIs. The goal is to ensure that every exported recording file includes specific metadata tags indicating its legal hold status, which is critical for our chain of custody requirements in the UK jurisdiction.
We are using the POST /api/v2/recordings/bulkexport endpoint. When we include the metadata array in the request body with custom key-value pairs for legal hold IDs, the API consistently returns a 422 Unprocessable Entity error. The error response body is somewhat generic:
{
"code": "invalid_argument",
"message": "The request body is invalid.",
"errors": [
{
"code": "invalid_metadata_format",
"message": "Metadata keys must be alphanumeric and under 50 characters."
}
]
}
However, our metadata keys are strictly alphanumeric, well under the character limit, and we have verified this with multiple test cases. For example, legal_hold_id_12345 is a valid key. This issue appears only when we attempt to attach recordings from digital channels like WhatsApp or Web Chat. Standard voice recordings export without any issues, even with the same metadata structure.
We are running this from a London-based server, using the Node.js SDK version 2.15.0. The environment is Genesys Cloud EU1. We have checked the audit logs, and the job creation request is received but immediately rejected before any processing begins.
Is there a hidden constraint on metadata for digital channel recordings that is not documented in the standard API reference? Or could this be related to how the system handles PII redaction metadata conflicts? We need a reliable way to tag these files for legal compliance without manual intervention. Any insights into why the validation fails specifically for digital channels would be greatly appreciated.
