webassembly XmlListModel not working

[poucz]

Hello,
I have test program, I work fine in normal desktop.
When I complile it with webassembly, XmlListModel not load data.
In console I see :
qml: XML Status change 2 error:

So XmlListModel not go to state 1 (Ready state), I dont know why.
In web browser I see query "http://127.0.0.1/text.xml" and good response (xml).

What is wrong?
Thank you

Rectangle{
    XmlListModel {
        id: xmlModel
       source: "http://127.0.0.1/text.xml"
        query: "/cross/cros"
        XmlRole { name: "time";        query: "@time/string()" }
        onStatusChanged: {
            console.log("XML Status change "+status+" error:"+errorString())
        }
    }


    ListView {
        id:view
        anchors.fill: parent
        model: xmlModel
        delegate: Text {
            text: time
        }
    }
}
