Solace nodejs api to retrieve message from message spool Queue - node.js

Question

While doing connect through the Nodejs api to the Solace message persistence queue, we encounter error:
{"message":"Consumer is not supported by router for this client","name":"OperationError","subcode":3,"reason":null}
on using the Solace Node.js API sample to connected to the Persistence Message Queue with the Web Message URI using soladmin.
consumer.connect = function (argv) {
if (consumer.session !== null) {
consumer.log('Already connected and ready to consume messages.');
return;
}
// extract params
//if (argv.length < (2 + 3)) { // expecting 3 real arguments
if (argv.length < 4) {
consumer.log('Cannot connect: expecting all arguments' +
'[<protocol://host[:port]>, <client-username>, <message-vpn>, <client-password>].\n' +
'Available protocols are ws://, wss://, http://, https://');
process.exit();
}
var hosturl = argv[0] //argv.slice(2)[0];
consumer.log('Connecting to Solace message router using url: ' + hosturl);
//var usernamevpn = argv.slice(3)[0];
var username = argv[1]//usernamevpn.split('#')[0];
consumer.log('Client username: ' + username);
var vpn = argv[2]//usernamevpn.split('#')[1];
consumer.log('Solace message router VPN name: ' + vpn);
var pass = argv[3]//argv.slice(4)[0];
// create session
try {
consumer.session = solace.SolclientFactory.createSession({
// solace.SessionProperties
url: hosturl,
vpnName: vpn,
userName: username,
password: pass,
});
} catch (error) {
consumer.log(error.toString());
}

Answer 1

The message "Consumer is not supported by router for this client" indicates that the issue is on the remote end.
Check if the client-profile allows the client to receive guaranteed messages. Otherwise, there may be a problem with the message spool that prevents the message broker from providing guaranteed messaging service.
The code snippet in the question is for initiating a connection only, and has nothing to do with connecting to the queue. The operation that failed should be
consumer.messageConsumer.connect();
