ProxyConnectionError when connecting as Anonymous - fiware-orion

Question

I have developed an operator to retrieve information from Orion Context Broker.
It works perfectly when I'm loggin but if I try to enter as anonymous (with the embedded URL) in a incognito window, the operator raises the next error:

This is the code:
var doInitialSubscription = function doInitialSubscription() {
this.subscriptionId = null;
this.ngsi_server = MashupPlatform.prefs.get('ngsi_server');
this.ngsi_proxy = MashupPlatform.prefs.get('ngsi_proxy');
this.connection = new NGSI.Connection(this.ngsi_server, {
ngsi_proxy_url: this.ngsi_proxy
});
console.log("Send initial subscription");
var types = ['SMARTMETER'];
var entityIdList = [];
var entityId;
entityId = {
id: '.*',
type: 'SMARTMETER',
isPattern: true
};
entityIdList.push(entityId);
var attributeList = null;
var duration = 'PT3H';
var throttling = null;
var notifyConditions = [{
'type': 'ONCHANGE',
'condValues': condValues
}];
var options = {
flat: true,
onNotify: handlerReceiveEntity.bind(this),
onSuccess: function (data) {
console.log("Subscription success ID: "+data.subscriptionId);
this.subscriptionId = data.subscriptionId;
this.refresh_interval = setInterval(refreshNGSISubscription.bind(this), 1000 * 60 * 60 * 2); // each 2 hours
window.addEventListener("beforeunload", function () {
this.connection.cancelSubscription(this.subscriptionId);
}.bind(this));
}.bind(this),
onFailure: function(data) {
console.log(data);
}
};
console.log("Now creating subscription...");
this.connection.createSubscription(entityIdList, attributeList, duration, throttling, notifyConditions, options);
};
Any idea of what is wrong?

According to user comments on the question, updating to Orion 0.19.0 (following the DB upgrade procedure detailed here) solves the problem.
