Problem
PureCloudPlatformClientV2 doesn’t expose a clean hook for opcode compliance checking during the WebSocket handshake phase. We’re trying to intercept control frames on the event stream before they hit our processing queue. The goal is to transform payloads, apply routing overrides, and sync with our security gateway. websockets library requires manual frame parsing for opcode=0x08 control frames. We’ve built a custom atomic handler to manage the frame manipulation with max_interceptors=10, but the buffer overflow verification pipeline keeps rejecting valid frames. Honestly the docs are thin on this.
Code
import asyncio
import websockets
from purecloudplatformclientv2 import Configuration, PlatformClient
config = Configuration()
client = PlatformClient(config)
token = client.auth.get_oauth_token()
async def intercept_handler(ws, path):
max_interceptors = 10
async for message in ws:
if message.opcode == 0x08:
payload_matrix = {"frame_type": "close", "routing_override": True}
if len(message.data) > 125:
await ws.close(1008, "Policy violation")
callback_gateway.sync(payload_matrix)
audit_log.write({"latency_ms": 12, "status": "intercepted"})
Error
The platform returns a 1002 Protocol Error when the transformation matrix tries to reassemble fragmented frames. PureCloudPlatformClientV2 handles the auth fine, but the underlying transport layer drops the sequence number during the reassembly trigger. The SDK throws websockets.exceptions.ConnectionClosedError: code = 1002. It’s completely halting the audit log generation.
Question
How do we properly wire the opcode compliance checking without breaking the automatic reassembly triggers? We need to keep the max interceptor count under the limit while tracking frame processing rates. The validation logic keeps failing on the buffer verification pipeline. Stuck on the reassembly trigger.
