消息框不显示

[sangyuxiaowu]

执行消息框提示后，如果不加入await Task.Delay(2000);将直接不显示消息框，如下：

static async Task<Output> change_models(Input input)
{
    var models = Utils.config?.Models?.Select(x => x.Name).ToList();
    if (models == null)
    {
        throw new Exception("Failed to fetch models from the server.");
    }

    string server = Textbox.Payload(input.Data[0]);
    string model = Dropdown.Payload(input.Data[1]).Single();
    if (server == "")
    {
        throw new Exception("Server URL cannot be empty.");
    }

    // 取得模型是第几个
    var index = models.IndexOf(model);
    if (index == -1)
    {
        throw new Exception("Model not found in the list of available models.");
    }
    if (Utils.config.Current == index)
    {
        // 没有切换模型
        return gr.Output(gr.Dropdown(choices: models, value: model, interactive: true));
    }
    var res = await Utils.client.PutAsync($"{server}/models/{index}/switch", null);
    // 请求失败
    if (!res.IsSuccessStatusCode)
    {
        // 错误信息未返回
        gr.Warning("Failed to switch model.");
       //await Task.Delay(2000);
        return gr.Output(gr.Dropdown(choices: models, value: models[Utils.config.Current], interactive: true));
    }
    Utils.config.Current = index;
    return gr.Output(gr.Dropdown(choices: models, value: model, interactive: true));
}
