client.findResources() is failing to discover the resources

[nagineni]

Step1: Run client which calles client.findResources() periodically.

var device = require( "iotivity-node" )();

device.configure( {
    role: "client",
    connectionMode: "acked"
} ).then(
    function() {
        discoverResources();
    },
    function( error ) {
        console.log( "Client: device.configure() failed with " + error );
    } );

device.client.addEventListener( "resourcefound", function( event ) {
    console.log( "Discovered resource(s) via the following event:\n" +
        JSON.stringify( event, null, 4 ) );
} );

function discoverResources() {
    device.client.findResources().then(
        function() {
            console.log( "Client: findResources() successful" );
        },
        function( error ) {
            console.log( "Client: findResources() failed with " + error +
                " and result " + error.result );
        } );
    notifyObserversTimeoutId = setTimeout(discoverResources, 5000);
}

Step2: Run the server without resource registration.

var device = require( "iotivity-node" )();

device.configure( {
        role: "server",
        connectionMode: "acked",
        info: {
            uuid: "Test Server",
            name: "server-example",
            manufacturerName: "Intel",
            firmwareVersion: "0.0.1",
        }
} );

Step 3(optional): Run an another server that register the resource. e.g. https://github.com/otcshare/iotivity-node/blob/master/js/high-level-server-example.js

Outcome: Check the output at client side

Client: findResources() failed with Error: findResources: failed to cancel previous handle and result 255
