错误以文本形式从Gmail获取pdf附件

Question

我需要帮助解决此问题。我收到没有记录的错误。

阿比的启用和指令被随后 原始讯息： Get pdf-attachments from Gmail as text

我得到错误：

var blob = attachments[0].getAs(MimeType.PDF);

从应用/转换八位字节流应用程序/ pdf不支持。 （第16行，文件 “血乳酸血乳酸”）

原始代码没有改变：

/** 
    * Get messages labeled 'templabel', and send myself the text contents of 
    * pdf attachments in new emails. 
    */ 
function myFunction() { 

    var threads = GmailApp.search('label:invoices-parsed'); 
    var threadsMessages = GmailApp.getMessagesForThreads(threads); 

    for (var thread = 0; thread < threadsMessages.length; ++thread) { 
    var message = threadsMessages[thread][0]; 
    var messageBody = message.getBody(); 
    var messageSubject = message.getSubject(); 
    var attachments = message.getAttachments(); 

    var blob = attachments[0].getAs(MimeType.PDF); 
    var filetext = pdfToText(blob, {keepTextfile: false}); 

    GmailApp.sendEmail(Session.getActiveUser().getEmail(), messageSubject, filetext); 
    } 
}

尝试设置附接到 “申请ication/PDF” 的的contentType。

var attachments = message.getAttachments(); 
attachments[0].setContentType("appl‌​ication/pdf");
