Description

Instead of sending the content, ContentService.createTextOutput returns a 404 error page when the content to send is large. Context: I am trying to send a Google Document converted as PDF.

It used to work before today.

Code

function doPost(e) {
  var docId = "XXXX";
  var file = DocumentApp.openById(docId);
  var fileData = file.getAs('application/pdf');
  var generatedFiles = [];
  
  generatedFiles.push({
      result: fileData.getBytes(),
      mimeType: 'application/pdf',
      fileId: file.getId()
  });
  
  return ContentService.createTextOutput(
      JSON.stringify(generatedFiles)
  );
}

Output

Returns a 404 page approximately 90% of the time (for the exact same document, so the file length does not seem to be the problem). Seems to work in some rare cases.
