我尝试使用addText(text)来创建文本，但是当我点击执行按钮时，没有任何反应。

以下是代码的片段：

button6.onClick = function() {
    addText();

    function addText() {
        app.beginUndoGroup("My Process");
        var comp = app.project.activeItem;
        var selectedlayer = comp.selectedLayers[0];
        if (comp == null) {
            alert("No composition selected");
        }
        if (comp.selectedLayers[0] == null) {
            alert("Select the layer");
        }
        var outpoint = comp.selectedLayers[0].outPoint;
        var inpoint = comp.selectedLayers[0].inPoint;
        var duration = outpoint - inpoint;
        var textLayer = comp.layers.addText(text);
        var sourceText = textLayer.property("Source Text").value;
        sourceText.fontSize = 100;
        sourceText.font = Arial;
        textLayer.property("Source Text").setValue(sourceText);
        textLayer.adjustmentLayer = false;
        textLayer.inPoint = inpoint;
        textLayer.label = 1;
        comp.layer(1).moveBefore(selectedlayer);
        app.endUndoGroup();
    }
}

我尝试使用addBoxText(text)来创建文本，但结果是一样的。
