Pushing a new script definition through the deployment pipeline and hitting a hard 422 on POST /api/v2/federation/agent-scripting/scripts. Platform’s running v24.10.2 in ap-northeast-1. The payload validates fine locally against the OpenAPI spec, but the gateway drops it immediately.
{
"name": "Outbound Callback Sync",
"content": [
{
"type": "prompt",
"text": "Confirming callback for ${interaction.customAttributes.ticket_id}",
"responseOptions": ["Yes", "No"],
"required": true
}
]
}
Response back is a validation error pointing at content[0].text. The parser claims the interpolation syntax is malformed. Tried escaping the dollar sign, tried wrapping in double quotes, still bombs. UI editor doesn’t even blink at it. Something’s stripping the interaction. prefix before the validation layer runs.
The event payload maps correctly, but the script deployment step fails before the interaction even starts. Pipeline’s doing jack all while this hangs.
Workaround’s just baking the script directly in the console and pulling the scriptId into the Terraform state file. Doesn’t play nice with infra-as-code, but keeps the CI runner green. Anyone else seeing the federation layer choke on interaction. variable paths during bulk script pushes?

Logs show it’s hitting scripting-validation-service and returning INVALID_REFERENCE_PATH. Guessing the regex checker is outdated.
The 422 usually hits because the scripting engine dropped support for the interaction.customAttributes. namespace in v24.10. Schema validation got stricter. You’ll need to swap that path for the direct ${custom.ticket_id} syntax. The platform expects custom data to be referenced flat under the custom scope. Just a namespace shift. Nothing complex.
Here’s how the prompt node should be structured before deployment:
{
"type": "prompt",
"text": "Confirming callback for ${custom.ticket_id}",
"responseOptions": ["Yes", "No"],
"required": true
}
Make sure the attribute actually exists in the conversation context before the script engine parses it. If you are routing this through a WebSocket notification stream or an API handoff, the custom data needs to be attached to the interaction payload first. You can verify the exact schema expectations by calling GET /api/v2/federation/agent-scripting/scripts/{scriptId} on a working template. The Rust serde deserializer will flag the mismatch immediately if the content array misses the required flag or uses an unsupported interpolation pattern. Check your webhook payload structure next.
The namespace shift breaks when the SBC config pushes policies through the Teams admin center. You’ll hit a vague gateway timeout on large payloads. Run Get-CsOnlineSession in PowerShell to check the scope.
Skip the script payload entirely and map the attribute through the SBC config instead. 2024-10-24 14:32:11 ERROR payload.validation... means the gateway rejected the nested path. "customMapping": "ticket_id" works fine. Validation clears after that.
Problem
Switching to ${custom.ticket_id} clears the schema validation, but that’s where the real headache starts. The scripting engine doesn’t magically pull custom attributes from the interaction metadata unless you explicitly push them into the script context first. A lot of folks update the script, deploy it, and then wonder why the prompt renders as an empty string during the call. It’s a silent failure.
You have to inject the data via the conversations data API before the script node evaluates. If you’re triggering this from a webhook or an external system, the payload has to match the key exactly.
// POST /api/v2/conversations/{conversationId}/data
{
"data": {
"ticket_id": "TICK-12345"
}
}
Without that call, the ${custom.ticket_id} reference resolves to nothing. The 422 goes away, but the agent sees a blank prompt. You’ll get a scripting.node.execution.failed event in the event stream if the reference is completely broken, but missing data usually just logs as a warning. Verify the data injection timing in your middleware.
PureCloudPlatformClientV2 handles the script deployment but it won’t magically hydrate those custom attributes unless you explicitly map them during the flow initialization. You’re spot on about the ${custom.ticket_id} syntax, but the real fix lives in the Node client setup. You’ll need to pass the attributes through the interaction context before the script engine even touches the payload.
Here’s how I patch it in our deployment scripts:
const platformClient = require('purecloud-platform-client-v2');
platformClient.AuthApi.initClient({
clientId: 'your_client_id',
clientSecret: 'your_client_secret',
baseUri: 'https://api.mypurecloud.com'
});
const scriptPayload = {
name: "Outbound Callback Sync",
content: [{
type: "prompt",
text: "Confirming callback for ${custom.ticket_id}",
responseOptions: ["Yes", "No"]
}],
contextMapping: {
source: "interaction",
target: "script.custom"
}
};
Watch the contextMapping block. If that’s missing the platform drops a 422 because the resolver can’t find the scope. Run a quick POST /api/v2/federation/agent-scripting/scripts with the scripting:write scope and it’ll stick. PureCloudPlatformClientV2 expects the mapping object nested right there with source and target defined. Just double check your webhook timeout settings before you push. The resolver hangs if the TTL drops below 300.
