Just noticed that the POST /api/v2/agent-scripts endpoint returns a 400 error when injecting BYOC trunk metadata into script variables. The payload validates fine in Swagger, but the production instance rejects it with Invalid property: trunkGroupId. This is happening across our APAC region trunks, specifically when trying to pass the outbound_trunk_id for call routing logic.
We are using the standard Genesys Cloud SDK v2.0. The error persists even after verifying that the trunk group IDs match exactly with those returned by GET /api/v2/trunks. It seems like the scripting engine does not recognize the BYOC trunk metadata fields, or there is a mismatch in the schema validation.
“Agent scripts can reference trunk metadata for outbound routing decisions. Ensure the trunk group ID is correctly formatted as a UUID.”
Has anyone else encountered this issue with BYOC trunks? We need this for our failover logic, so any insights would be appreciated.
{
"trunkMetadata": {
"groupId": "string",
"outboundTrunkId": "string"
}
}
The documentation actually says that the agent-scripts endpoint does not accept raw trunk identifiers directly in the root level of the script payload. The 400 error with Invalid property: trunkGroupId indicates that the API schema is rejecting the key because it expects the trunk data to be nested under a specific metadata object or passed via a different mechanism entirely.
In my experience handling bulk exports and legal discovery requests, the recording metadata chain is strictly enforced. When you inject variables into scripts, the system validates them against the current session context. If you are trying to force the outbound_trunk_id into the script variables for routing logic, you should not be doing it via the script definition itself. Instead, you need to handle this at the routing campaign level or via the conversation API once the media stream is established.
The agent-scripts API is designed for content delivery, not for dynamic routing configuration based on trunk groups. The validation failure happens because trunkGroupId is not a defined property in the Script schema. To achieve the desired routing logic, you should use the routing:campaign:write scope to set the outbound trunk preference in the campaign configuration, or use a flow decision step that evaluates the conversation’s trunk information dynamically.
For legal hold purposes, ensure that any custom metadata you do capture is tagged correctly in the recording export job. If you force invalid properties into the script, the entire interaction might fail to log correctly in the audit trail. Stick to the defined schema for scripts and move the trunk logic to the flow or campaign settings. This keeps the chain of custody intact and avoids API rejection.
{
"trunkMetadata": {
"groupId": "your-group-id",
"outboundTrunkId": "your-trunk-id"
}
}
You need to wrap the identifiers in that specific object. The root level rejects raw trunkGroupId. I hit this exact 400 error when wiring up ServiceNow incident creation via Data Actions. The schema strictly enforces that nested structure.
Have you tried validating the JSON structure against the latest OpenAPI specification for the agent-scripts endpoint before submission? The 400 error regarding Invalid property: trunkGroupId typically indicates that the payload contains a root-level key that the schema explicitly rejects. The API expects trunk-related identifiers to be encapsulated within a dedicated metadata object, not exposed at the top level of the script configuration.
From a performance monitoring perspective, ensuring clean data ingestion is critical for accurate queue activity reporting. If the script fails to load due to schema violations, the associated conversation metrics will not populate correctly in the Agent Performance views. This creates gaps in the historical data used for workforce management forecasting and compliance audits. The suggestion above regarding the nested trunkMetadata object is correct. The structure should resemble the following configuration to satisfy the validation logic:
{
"scriptId": "your-script-id",
"trunkMetadata": {
"groupId": "apac-trunk-group-id",
"outboundTrunkId": "apac-trunk-001"
}
}
It is important to verify that the outboundTrunkId matches the exact identifier used in the BYOC trunk configuration within the Genesys Cloud administration console. Mismatches here can cause silent failures in routing logic, even if the script loads successfully. Furthermore, check that the integration settings for the external CRM do not override these variables during the interaction context population. The documentation suggests that explicit configuration within the integration settings is required for external CRM attributes to populate automatically. Relying on the script to fetch these values without proper nesting often leads to the timeout issues previously discussed in the SIP trunk registration threads. Ensuring the payload adheres strictly to the nested schema prevents these validation errors and maintains data integrity across the performance dashboards.
