Error compiling builtin: Invalid private name ‘@createResolvingFunctions’
Error compiling builtin: Invalid private name ‘@createResolvingFunctions’

发送http请求的时候，出现这两句错误日志，然后没有任何响应了
log.rar (1.8 KB)

论坛中并没有找到类似的问题，求助引擎开发组

贴上部分请求代码

public static async LoadText(url: string, data?: IDictionary<string, any>, method: string = "GET"): Promise<any> {
    var promise = new Promise<any>(function (resolve, reject) {
        let isreturn = false;
        setTimeout(() => {
            if (!isreturn) {
                reject(new Error("网络连接已超时"));
                isreturn = true;
            }
        }, 5000);
        let datastr = null;
        if (data) {
            datastr = data.ToUrl();
        }
        var client = cc.loader.getXMLHttpRequest();//new XMLHttpRequest();
        if (method === "GET") {
            if (datastr) {

    });

    return promise;

我在stackoverflow上看到一个类似的问题

有可能是Promise的问题，在iOS一些版本中有bug

不使用Promise的话，有响应了。已经弃用Promise
