WebsocketApi Lambda and connect ECONNREFUSEDlg...
Hello,
I've been setting up Websocket API with Lambda and I received following error:
```
<message-id> INFO Error: connect ECONNREFUSED <ip>
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1300:16) {
errno: -111,
code: 'ECONNREFUSED',
syscall: 'connect',
address: <ip>,
port: 80,
'$metadata': { attempts: 1, totalRetryDelay: 0 }
```
Env is a Node18 and Postman (ws) as a client.
Lambda's code:
```
import { ApiGatewayManagementApiClient, DeleteConnectionCommand,PostToConnectionCommand } from "@aws-sdk/client-apigatewaymanagementapi";
const api = new ApiGatewayManagementApiClient({endpoint: 'wss://<id>.execute-api.<region>.amazonaws.com/production',
region: 'eu-central-1'
})
export const handler = async (event) => {
console.log(event);
const {routeKey, connectionId} = event?.requestContext
let msg;
console.log(`Request key is ${routeKey} and connectionID is ${connectionId}`)
switch(routeKey){
case '$connect':
msg = 'connected My friend';
break;
case '$disconnect':
msg = 'disconnected my friend';
break;
case 'message':
try{
await replyToMessage(connectionId, 'RAMP PAM PAM')
}catch(e){
console.log('EXEPTION ALARM')
console.log(e)
}
break;
default:
console.log('something bad happened', routeKey);
break;
}
// TODO implement
const response = {
statusCode: 200
};
return response;
};
const replyToMessage = (ConnectionId, message) =>{
const data = {message};
const cmd = new PostToConnectionCommand({
ConnectionId,
Data: Buffer.from(JSON.stringify(data))
})
const result = api.send(cmd);
console.log(result)
return result;
}
```

Thank you in advance,
