PureCloudPlatformClientV2 rejects the share payload on the Agent Assist WebSocket endpoint whenever the optimistic update matrix crosses the assist gateway constraints. We’re porting the Python SDK example to Node.js, and we’re routing note content references through a custom note sharer, but the atomic SEND operation keeps failing format verification. The conflict resolution directive should handle the auto version increment triggers, yet the collaborator permission verification pipeline blocks the push. Content sanitization checking passes locally, but the gateway throws a 400 with {"error": "max_note_size_exceeded"} even though the byte count stays under the limit. We’ve wired up webhook callbacks to sync share events with our external case system, and the latency tracking shows a 350ms delay before the audit log entry drops. The sync accuracy rate drops to 60% when scaling past ten concurrent sessions. Here’s the exact structure we’re pushing:
{
"action": "SEND",
"noteId": "assist-note-8842",
"contentReference": "raw-text-payload",
"optimisticUpdateMatrix": { "version": 3, "conflictDirective": "overwrite" },
"sanitizationCheck": true,
"collaboratorPermissions": ["viewer", "editor"]
}
The version increment trigger isn’t firing on the second iteration. Gateway logs show the packet dropping right after the webhook callback fires.
Problem
The SEND opcode rejects the payload because the note reference doesn’t have the required sharedContent wrapper.
Code
ws.send(JSON.stringify({ type: 'share', sharedContent: { id: noteId, type: 'agent-assist/note' } }));
Error
400 validation_failed on the assist gateway.
Question
Check the OTel span for the raw binary frame.
The suggestion above about the sharedContent wrapper hits the mark. The assist gateway really does choke without it. Broken payloads cause the gamification engine to register null values for the assist metric. That flatlines the daily leaderboard and kills agent motivation pretty fast. Supervisors end up chasing empty quality scores because the note never actually reaches the scoring queue. When agents don’t see their effort reflected in the weekly rankings, engagement drops across the whole floor.
You’ll need to wrap the reference exactly like the example, but the type field has to match what the contest metric is listening for. The internal setup tracks agent_assist_notes_shared, and it only fires when the WebSocket payload passes the schema check cleanly. A missing wrapper just throws a validation error that nobody knows how to fix until the contest window closes.
ws.send(JSON.stringify({
type: 'share',
sharedContent: {
id: noteId,
type: 'agent-assist/note',
metadata: { contestId: 'daily_quality_win' }
}
}));
Does the Architect flow require a separate data action to catch that metadata, or does the gamification platform pull it automatically? The documentation isn’t super clear on the boundary between the assist gateway and the scoring engine. The error log just mentions a mismatched schema somewhere, which leaves a lot to guesswork. Usually the platform handles the scoring sync on its own, but the midnight reset sometimes breaks the handshake.
Agents can’t figure out why their assist scores stall out. Fixing the payload structure usually clears it up. Just watch the midnight reset window. The contest engine recalculates everything then, and a stuck WebSocket connection will double-count notes if it reconnects too fast.
