match()不处理数字字段

我试图通过使用正则表达式过滤电子邮件列中具有特定单词的行来执行操作。

问题是 match() 产生以下错误

TypeError: Cannot find function match in object 1234. (line 25, file "Code")

我的代码

    function smartDelete() {
    // smartDelete settings goes here, 
    var badDomains = ["bad\\.com", "red\\.com"];

    var emailColumnNumber = 2;

    var regExpModifiers = "i";

    // Gain access data in the sheet
    var sheet = SpreadsheetApp.getActiveSheet();
    var rows = sheet.getDataRange();
    var numRows = rows.getNumRows();
    var values = rows.getValues();
    var rowsDeleted = 0;
    var Action = false;

    // delete procedure
    for (var i = 0; i <= numRows - 1; i++) {
        var row = values[i];
        Action = false;

        // check bad domains
        for (var j = 0; j <= badDomains.length - 1; j++) {
            var myPattern = new RegExp(badDomains[j], regExpModifiers);
            var status = row[emailColumnNumber].match(myPattern);
            if (status) {
                // match found, mark this row for delete
                Action = true;
                break;
            };
        };

        // execute delete.
        if (Action) {
            sheet.deleteRow((parseInt(i) + 1) - rowsDeleted);
            rowsDeleted++;
        };
    };
}
