当人们几乎同时提交表单时，我最近遇到了我认为是并发问题的问题，这导致谷歌表单的数据丢失。我已经在使用 Lock 服务来防止这个问题，但我似乎仍然有问题。http://googleappsdeveloper.blogspot.com/2011/10/concurrency-and-google-apps-script.html
表单目前有 onFormSubmit 触发器：formSubmitReply 和 logMessage。formSubmitReply 向提交表单的人发送确认信息，并且 logMessage 应该在单独的电子表格中备份信息，以防常规电子表格中的行被破坏。它应该从 formSubmit 事件中提取值，然后将其附加到“日志”表中。
我已经包含了脚本的所有当前代码，并用占位符替换了电子邮件。我可以获得一些帮助来识别代码中可能阻止表单在表单中记录行的任何错误吗？

var sheet=SpreadsheetApp.getActiveSheet();
var rowWidth=sheet.getLastColumn();
var row=sheet.getRange(1,1,1,rowWidth).getValues();//this is the first row
for ( i in row[0]){
var name=row[0][i];
if(name == colName || new RegExp(colName,'i').test(name)){
return parseInt(i)+1;
}
}
return -1
}

/*This is for Student Volunteer auto-confirmation*/
var ss,sheet, rowWidth, headers, rowWidth,curRow, values, greeting, robot, msg, space, newline;
curRow=e.range.getRow();
