string - 当我用“+”分割行时，广告脚本将字符串 var 转换为矩阵

Question

当我运行此代码时，一切正常：

  var headerKeys = "conversion_action.firebase_settings.event_name,conversion_action.type,conversion_action.name,conversion_action.resource_name,conversion_action.third_party_app_analytics_settings.event_name,metrics.conversion_last_conversion_date".split(",");
  Logger.log(JSON.stringify(headerKeys));
  var range = sheet.getRange(1, 1, 1, headerKeys.length);
  range.setValues([headerKeys]);

比。当我将字符串分成两行时，出现错误：

  var headerKeys = "conversion_action.firebase_settings.event_name,conversion_action.type,conversion_action.name,"+
      "conversion_action.resource_name,conversion_action.third_party_app_analytics_settings.event_name,metrics.conversion_last_conversion_date".split(",");
  Logger.log(JSON.stringify(headerKeys));
  var range = sheet.getRange(1, 1, 1, headerKeys.length);
  range.setValues([headerKeys]); //line 65

无法将 Array 转换为 number[][]。（文件 Code.gs，第 65 行）
