Parse javascript deleteAll() 只删除 20 个对象，即使我的限制是 1000 个？

Question

我试图从服务器上删除超过 1 天的图像，但出于某种原因，即使我将限制设置为 1000，它也只删除了 20 张图像。

代码如下：

Parse.Cloud.job("deleteImages", function(request, status) {

  Parse.Cloud.useMasterKey();

    //Get yesterday
    var ts = Math.round(new Date().getTime() / 1000);
    var tsYesterday = ts - (24 * 3600);
    var dateYesterday = new Date(tsYesterday*1000);

    //Query with limit 1000
    var query = new Parse.Query("image");
    query.lessThan("createdAt", dateYesterday);
    query.limit(1000);


    query.find({
        success: function(result) {
          Parse.Object.destroyAll(result, {
            success: function() {
              status.success("Delete job completed");
              console.log("Success");
            },
            error: function(error) {
              if (error.code == Parse.Error.AGGREGATE_ERROR) {
                for (var i = 0; i < error.errors.length; i++) {
                  console.log("Couldn't delete " + error.errors[i].object.id +
                    "due to " + error.errors[i].message);
                    status.error("Delete error :" + error);
                }
              } else {
                status.error("Delete error :" + error);
                console.log("Delete aborted because of " + error.message);
              }
            },
          });
          status.success("Delete job completed");
        },
        error: function(error) {
            status.error("Error in delete query error: " + error);
            alert('Error in delete query');
        }
    });
});

如有任何帮助，我们将不胜感激！谢谢

对于遇到同样问题的其他人来说，这个解决方案真的很奇怪，我不明白它为什么有效。但是，通过从代码中完全删除 status.success() 似乎可以完成工作。我收到一条错误消息“Failed with: success/error was not called”，但它仍然删除了 1000 张图像。

Parse.Cloud.job("deleteImages", function(request, status) {

    Parse.Cloud.useMasterKey();

    //Get yesterday
    var ts = Math.round(new Date().getTime() / 1000);
    var tsYesterday = ts - (24 * 3600);
    var dateYesterday = new Date(tsYesterday*1000);

    //Query with limit 1000
    var query = new Parse.Query("image");
    query.lessThan("createdAt", dateYesterday);
    query.limit(1000);


    query.find({
        success: function(result) {
            Parse.Object.destroyAll(result, {
                success: function() {
                    console.log("Success");
                },
                error: function(error) {
                    if (error.code == Parse.Error.AGGREGATE_ERROR) {
                        for (var i = 0; i < error.errors.length; i++) {
                            console.log("Couldn't delete " + error.errors[i].object.id +
                            "due to " + error.errors[i].message);
                        }
                    } else {
                        console.log("Delete aborted because of " + error.message);
                    }
                }
            });
        },
        error: function(error) {
            status.error("Error in delete query error: " + error);
        }
    });
});

"Calling status.success() or status.error() at any point will terminate the job."
