Data Action 400 on gamification contest score sync

NICE CXone API & Integrations
1

The weekly leaderboard reset is supposed to refresh agent KPIs automatically, but the Data Action in our Architect flow keeps failing right after the midnight window. We’re running Genesys Cloud 2024-06 release with a custom integration pulling from /api/v2/analytics/conversations/summary to feed the gamification contest scores. The flow hits a 400 Bad Request on the post step, and the console just shows a generic validation error that isn’t really pointing to anything specific. Agent motivation is taking a hit since the performance badges aren’t updating, and the HR dashboard is stuck on last week’s numbers.

The payload looks fine in the preview, but something in the JSON schema mapping is throwing a fit when the contest ID gets appended. Do I need to manually map the date range parameters or is the system just rejecting the request because of a missing header? The integration logs show a weird validation mismatch followed by a timeout on the retry loop, and the gamification profile sync is doing jack all. Running this in the Tokyo prod environment with API v2.21.0… {“errorCode”: “INVALID_REQUEST_BODY”, “message”: “Field ‘start_time’ exceeds max length”, “traceId”: “gc-int-88a2f1”}

Problem

You’re pushing a flattened config snapshot instead of the raw contest payload, and the backend chokes on that nested structure.

Fix

  • Strip the outer brackets from your restore job output
  • Hit /api/v2/gamification/contests/{contestId}/scores with application/json and gamification:write scope
{
 "agent_id": "a1b2c3",
 "score": 95,
 "contest_id": "leaderboard_weekly"
}

Error

Validation clears once the shape matches.

Question

Dump the full 400 payload.

Schema validation was totally blocking us. Thanks for the pointer. The bracket stripping actually fixed the 400. We were wrapping the scores array in an extra object layer that the gamification endpoint rejects. Here’s the exact shape that clears validation:

{
 "scores": [
 {
 "userId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
 "score": 150
 }
 ]
}

Make sure your Lambda handler strips that wrapper before hitting /api/v2/gamification/contests/{contestId}/scores. You’ll also need the gamification:write scope on your OAuth token. Don’t batch more than 500 score objects per request or the gateway will silently drop the tail end of the array. We switched to an EventBridge rule that triggers a Step Function to chunk the analytics summary output instead of pushing it all at once. Runs clean now. Midnight resets are finally hitting the leaderboard.

The 400 happens because /api/v2/gamification/contests/{id}/scores rejects nested wrapper objects instead of a flat array.

It’s a quick fix in the Lambda handler. Just drop the outer braces before platformClient.gamificationApi.postGamificationContestScores().

{ "scores": [{ "userId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890", "score": 150 }] }

CloudWatch stops spamming validation errors after that.

{
 "scores": [
 {
 "userId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
 "score": 150
 }
 ]
}

That exact payload shape finally cleared the 400 Bad Request on the /api/v2/gamification/contests/{id}/scores endpoint. It’s been a pain tracking down how node-fetch v2 mangles the body in the Electron main process. Stripping that outer object and passing the raw scores array directly to platformClient.gamificationApi.postGamificationContestScores() fixed the schema validation crash. You’ll want to verify your OAuth bearer token has the view:gamification and edit:gamification scopes attached before the request fires. The Architect Data Action was choking on the nested JSON because the integration runtime expects a flat array structure, not a wrapped payload. Running a quick console.log(JSON.stringify(payload, null, 2)) in the renderer process before IPC transmission usually catches these serialization mismatches early. The midnight reset window now processes without throwing generic validation errors. Still debugging the WebSocket heartbeat drop on EU-West. Weird how the main process drops frames right after the contest sync fires.
