Google Sheet Script (Email to PDF) suddenly sending corrupt PDFs - pdf

Question

I have a Google Sheet Script that sends the page to an email as a PDF which has been working perfectly until yesterday. Suddenly it started sending corrupted PDF's that can not be opened.
The Script runs just fine, if just can not open up the PDF file as it says "Can Not Display - Invalid format".
Any ideas on why it may have stopped working?
function sendSheetToPdfwithA1MailAdress(){ // this is the function to call
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sh = ss.getSheets()[0]; // it will send sheet 0 which is the first sheet in the spreadsheet.
// if you change the number, change it also in the parameters below
var shName = sh.getName()
// This function uses a cell in the spreadsheet that names the file that is being saved as getfilename(). using this function will pull from a certain Cell (G4 in this case)
function getFilename() {
var spreadsheet = SpreadsheetApp.getActive();
var sheet = spreadsheet.getSheetByName('N1944E'); // Edit the sheet name as necessary
var cell = sheet.getRange('C8'); //Cell to pull file name from.
var filename = cell.getValue();
return filename;
}
sendSpreadsheetToPdf(0, shName, sh.getRange('C6').getValue(),"Air Attack Daily Fire Sheet " + getFilename() );
}
function sendSpreadsheetToPdf(sheetNumber, pdfName, email,subject, htmlbody) {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var spreadsheetId = spreadsheet.getId()
var sheetId = sheetNumber ? spreadsheet.getSheets()[sheetNumber].getSheetId() : null;
var url_base = spreadsheet.getUrl().replace(/edit$/,'');
var url_ext = 'export?exportFormat=pdf&format=pdf' //export as pdf
+ (sheetId ? ('&gid=' + sheetId) : ('&id=' + spreadsheetId))
// following parameters are optional...
+ '&size=A4' // paper size
+ '&portrait=true' // orientation, false for landscape
+ '&fitw=true' // fit to width, false for actual size
+ '&sheetnames=true&printtitle=false&pagenumbers=true' //hide optional headers and footers
+ '&gridlines=false' // hide gridlines
+ '&fzr=false'; // do not repeat row headers (frozen rows) on each page
var options = {
headers: {
'Authorization': 'Bearer ' + ScriptApp.getOAuthToken(),
}
}
var response = UrlFetchApp.fetch(url_base + url_ext, options);
var blob = response.getBlob().setName(pdfName + '.pdf');
if (email) {
var mailOptions = {
attachments:blob, htmlBody:htmlbody
}
MailApp.sendEmail(
email,
subject+" (" + pdfName +")",
"html content only",
mailOptions);
MailApp.sendEmail(
Session.getActiveUser().getEmail(),
" "+subject+" (" + pdfName +")",
"html content only",
mailOptions);
}
}

Answer 1

I had the exact same issue, but I just figured it out. The problem is here:
var url_base = ss.getUrl().replace(/edit$/,'') + "export?";
getUrl() appears to be returning a different version of the url than it was before. It now appends the following on the url: "ouid=###########&urlBuilderDomain=YOURDOMAIN" check it out yourself by using the logger.
That is causing an issue with the pdf export. So I built my own url address by replacing that line with the following:
var url_base = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/" + "export?";
It now seems to be working! Here's the full code that generates my blob:
function generatePDF(pdfName, sheet, portrait){
var token = ScriptApp.getOAuthToken();
var params = {
headers: {
'Authorization': 'Bearer ' + token,
},
'muteHttpExceptions' : true
};
var sheetId = sheet.getSheetId();
var ss = sheet.getParent();
// var url_base = ss.getUrl().replace(/edit$/,'') + "export?";
var url_base = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/" + "export?";
var url_ext = 'exportFormat=pdf' //export as pdf
+ '&format=pdf' //export as pdf
+ '&gid=' + sheetId
+ '&size=letter' // paper size
+ '&portrait=' + portrait // orientation, false for landscape
+ '&fitw=true' // fit to width, false for actual size
+ '&sheetnames=false' //optional headers and footers
+ '&printtitle=false' //optional headers and footers
+ '&pagenumbers=true' //page numbers
+ '&gridlines=true' // gridlines
+ '&fzr=true' // repeat row headers (frozen rows) on each page
var response = UrlFetchApp.fetch(url_base + url_ext, params);
var blob = response.getBlob().setName(pdfName + ".pdf");
return blob;
}

Try this:
function sendSpreadsheetToPdf(sheetNumber, pdfName, email,subject, htmlbody) {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var spreadsheetId = spreadsheet.getId()
var sheetId = sheetNumber ? spreadsheet.getSheets()[sheetNumber].getSheetId() : null;
var url_base = "docs.google.com/spreadsheets/d" + spreadsheetId + "/export?";
var url_ext = 'exportFormat=pdf&format=pdf' //export as pdf
+ (sheetId ? ('&gid=' + sheetId) : ('&id=' + spreadsheetId))
// following parameters are optional...
+ '&size=A4' // paper size
+ '&portrait=true' // orientation, false for landscape
+ '&fitw=true' // fit to width, false for actual size
+ '&sheetnames=true&printtitle=false&pagenumbers=true' //hide optional headers and footers
+ '&gridlines=false' // hide gridlines
+ '&fzr=false'; // do not repeat row headers (frozen rows) on each page
var options = {
headers: {
'Authorization': 'Bearer ' + ScriptApp.getOAuthToken(),
},
'muteHttpExceptions' : true
}
var response = UrlFetchApp.fetch(url_base + url_ext, options);
var blob = response.getBlob().setName(pdfName + '.pdf');
if (email) {
var mailOptions = {
attachments:blob, htmlBody:htmlbody
}
MailApp.sendEmail(
email,
subject+" (" + pdfName +")",
"html content only",
mailOptions);
MailApp.sendEmail(
Session.getActiveUser().getEmail(),
" "+subject+" (" + pdfName +")",
"html content only",
mailOptions);
}
}

Can you try this instead of your current blob declaration :
var blob = response.getBlob().getAs('application/pdf').setName(pdfName + ' .pdf');
