Question

我的问题是这样，我正在使用Parse云代码，并且有一个保存前触发器，如下所示：

Parse.Cloud.beforeSave("Ordenes", function(request, response) {
    console.log(request.object + " beforeSaveCalled");
    var query = new Parse.Query("Ordenes");
    var current = query.get(request.object.id, {
    success: function(object) {
        console.log(object + "This row");

        console.log(object.id + " object " + request.object.id + " request.object " + "exist?");

        if (object.get("MozoAdded") === false ) {
            console.log("correct return we can proceed");
//          const ordenLocation = object.get("Ubicacion");
//          const queryMozos = new Parse.Query("MozosLocation");
//          
//          queryMozos.near("MozoLocation1", ordenLocation);
//          
//          queryMozos.limit(1);
//          
//          const mozoToAdd = await queryMozos.find();
//          
//          console.log(mozoToAdd +" El mozo cerca es " + mozoToAdd[0].get("Name"));

//          object.set("MozoName", mozoToAdd[0].get("Name"));


            response.success();
        } else if (object.get("MozoAdded") === undefined) {
            console.log("Weird but not incorrect, proceed");
//          const ordenLocation = object.get("Ubicacion");
//          const queryMozos = new Parse.Query("MozosLocation");
//          
//          queryMozos.near("MozoLocation1", ordenLocation);
//          
//          queryMozos.limit(1);
//          
//          const mozoToAdd = await queryMozos.find();
//          
//          console.log(mozoToAdd +" El mozo cerca es " + mozoToAdd[0].get("Name"));
//          
//          object.set("MozoName", mozoToAdd[0].get("Name"));
            response.success();
        } else {
            console.log("Big nope, nope, nope");
            response.error("Esta orden ya fue asignada.");

        }
    },

    error: function(object, error) {
        response.success();

    }
    });

});

未注释注释的代码将引发此错误：

 Cloud Code not loaded:
 /usr/src/app/data/cloud/main.js:175
            const mozoToAdd = await queryMozos.find();
                                    ^^^^^^^^^^

SyntaxError: Unexpected identifier

我想做的是在MozosLocation表中找到最近的mozo，使用Orden [“ Ubicacion”]将其名称添加到我要保存的对象中。

正如您所见，我对js并不是很熟悉，并且解析指南并没有真正涵盖此类错误，因此，关于导致错误的原因有什么主意吗？帮助

It's available only at the Parse Server Version 3.0.0. Only this version fully supports promises and async/await, as you can see in its releases.

使用await解析云代码js引发语法错误
