How to use signal when using a repeater

[w.tkm]

Hi.
I want to use signal when using a repeater
I did it this way, but I can't do.

main.qml

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Row{
        anchors.top: parent.top
            Repeater{
            id: rowRect
            model: 3
            MyRect{
                width: 50
                height: 50
                color: "#444343"
                border.width: 1
                border.color: "gray"
            }
        }
    }

    Connections{
        target: rowRect.itemAt(0)
        function testSig(){
            console.log("get")
        }
    }
}

MyRectForm.qml

MyRectForm{
    signal testSig
    Connections{
        target: rectMouseArea
        function onClicked(){
            console.log("send")
            testSig()
        }
    }
}

MyRect.qml

Rectangle{
    id: systemRect
    property alias rectMouseArea: rectMouseArea

    MouseArea{
        id: rectMouseArea
        anchors.fill: parent
    }
}

When I click on the first rectangle, I want the signal to move, but it doesn't.
How do I do this?

@w-tkm Change to:

Connections{
    target: rowRect.count > 0 ? rowRect.itemAt(0): null
    function onTestSig(){
        console.log("get")
    }
}
