Cannot read property 'split' of undefined

[arpitagrawal0000]

can anyone help why I am getting this issue? here is my code:-

const signer = require('node-signpdf').default;
const  {plainAddPlaceholder} = require('node-signpdf/dist/helpers');

const action = async () => {
var pdfBuffer = fs.readFileSync('./test.pdf');
 pdfBuffer = plainAddPlaceholder({
    pdfBuffer,
    reason: 'I am the author',
    signatureLength: 1612,
  });
let p12Buffer = fs.readFileSync('./certificate.p12')
let pdf = signer.sign(pdfBuffer, p12Buffer);
fs.writeFileSync(__dirname + '/result.pdf', pdf);
}

action();

and i am getting this error.

Without a PDF that fails, I doubt it that someone would help.

@arpitagrawal0000 you are using a async function. so you have use await before call the method sign( ).

[zerobytes]

Here goes a pdf that fails, for me. Same error, same case. pdf that [pdf-that-fails.pdf…]()

@dipedro i doubt that your comment is correct, as there is no promise return in none of the methods.

[vbuch]

Yup. plainAddPlaceholder is synchronous so that's not the issue.

@zerobytes bad link?

Hi! check if your document is linearized, please visit: https://www.pdftron.com/blog/pdf-format/what-is-pdf-linearization/ The bug that exists is when the split is made, the "trailer" section is not found. Then it fails.

/home/hp/project/node_modules/node-signpdf/dist/helpers/plainAddPlaceholder/readRefTable.js const [objects, infos] = refTable.toString().split('trailer');

Same error here.. PDF that fails PDF 140mb Error: Cannot read property 'split' of undefined readRefTable.js#L48

[nfcaballaro]

@ankology if you edit the document, you can see in the first lines that your document is linearized

this issue occurs when you are using PDF-Lib to add or parse the PDF before the signing process.

{ useObjectStreams: false } to the save() method did the trick! in pdf-lib
