Trying to parse invalid object.

[Aizaz-ul-haq]

What were you trying to do?

I am trying to merge three pdf files. one of these files (find the attached file) can not be parsed and keeps returning the following errors:

Trying to parse invalid object: {"line":2327,"column":6,"offset":396013}) Invalid object ref: 15 0 R Trying to parse invalid object: {"line":2424,"column":6,"offset":473052}) Invalid object ref: 417 0 R E:\Me\example-project\BackEnd\falaya-backend\node_modules\pdf-lib\src\core\errors.ts:26but got instance of ${actual ? actual.constructor.name : actual}; ^ Error: Expected instance of PDFDict, but got instance of undefined The file is not encrypted, there could be some fields using x/y coordinates since it is being generated by a pdf signing software that could be causing this issue. but I am not sure.

The pdf file I am using is: pdf file

How did you attempt to do it?

document = await PDFDocument.load(document.buffer, { ignoreEncryption: true });

What actually happened?

I got the following errors: Trying to parse invalid object: {"line":2327,"column":6,"offset":396013}) Invalid object ref: 15 0 R Trying to parse invalid object: {"line":2424,"column":6,"offset":473052}) Invalid object ref: 417 0 R E:\Me\example-project\BackEnd\falaya-backend\node_modules\pdf-lib\src\core\errors.ts:26 but got instance of ${actual ? actual.constructor.name : actual}; ^ Error: Expected instance of PDFDict, but got instance of undefined

What did you expect to happen?

Load the pdf and merge all the documents in a single pdf file.

How can we reproduce the issue?

A little late, but I was having the same issue and this appears to be the root cause: https://github.com/Hopding/pdf-lib/issues/623#issuecomment-724654427
