为什么“ updateRecord”功能无法正常运行？

Question

我不确定这是怎么回事。代码在下面，在这里：https://studio.code.org/projects/applab/X4-WurQPCCvEeOYJqYRhps1o55VtifdyI7wAmGuPJKg是应用程序的链接，如果您想尝试的话。任何帮助表示赞赏。

var player = {};
onEvent("addNewRecordButton", "click", function() {
  //This code reads the database to create only one user per userID
  //If the userID already exists within the database, it does nothing
  readRecords("AllUserData", {UserID:(getUserId())}, function(records) {
      var count = records.length;
      if (count > 1) {
          
      } else if ((count == 1)) {
          
      } else {
      player.UserID = getUserId();
      player.Username = getText("usernameInput");
      createRecord("AllUserData", player, function(record) {
        
      });
      }
  });
});
onEvent("updateInformationButton", "click", function() {
  var player = {};
  player.UserID = getUserId();
  player.Username = getText("usernameInput");
  updateRecord("AllUserData", player.Username, function(record, success) {
    if (success) {
      setText("label4", "Record updated with id:" +record.id);
      setText("label3", player.Username);
    } else {
      write("Record NOT updated");
    }
  });
});
