We are deploying a voice bot integration using Genesys Cloud AppFoundry and NICE Cognigy. The infrastructure is managed via Terraform, so the environment provisioning is consistent, but the runtime behavior is unstable. The issue manifests as intermittent WebSocket connection drops between the Genesys Cloud platform and our AppFoundry container. When the connection drops, the audio stream experiences significant latency, sometimes up to 2 seconds, before the bot responds or the call disconnects.
The AppFoundry service is configured to handle the voice interaction. We are using the standard WebSocket handshake protocol. The connection is established successfully, and the initial init message is sent. However, after a few exchanges, the connection terminates unexpectedly. We have monitored the logs and noticed that the WebSocket state changes to CLOSED without a clear error code from the Genesys side.
Here is the relevant snippet from our Node.js server handling the WebSocket connection:
const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 8080 });
wss.on('connection', (ws) => {
console.log('Connection established');
ws.on('message', (data) => {
const msg = JSON.parse(data);
if (msg.type === 'init') {
ws.send(JSON.stringify({ type: 'ready' }));
} else if (msg.type === 'input') {
// Process voice input
console.log('Received input:', msg.payload);
// Simulate processing delay
setTimeout(() => {
ws.send(JSON.stringify({ type: 'output', payload: 'Testing latency' }));
}, 100);
}
});
ws.on('close', (code, reason) => {
console.log(`Connection closed with code: ${code}, reason: ${reason}`);
});
});
The logs show the connection closing with code 1001 (Going Away) or 1006 (Abnormal Closure) after approximately 30-60 seconds of inactivity or during heavy load. We have increased the keep-alive interval in the AppFoundry configuration, but the issue persists. We are using the genesys-cloud-websocket library for the client-side connection, but the drops seem to originate from the platform side.
Has anyone encountered similar issues with WebSocket stability in AppFoundry voice bots? Are there specific configurations or timeouts in Genesys Cloud that need to be adjusted to prevent these premature closures? We are looking for a code-level or configuration fix to stabilize the connection.
