Getting "DOMMatrix is not defined" error in Extract from PDF node

Describe the problem/error/question

Im using HTTP request node to get a PDF file and then using Extract from file node to extract the data from the PDF file. This was all working fine before, but now i’m getting a “DOMMatrix is not defined” error. When testing the workflow, the output from the HTTP request node is good (i see the binary file, I can download it and its a normal PDF file).

I did update our n8n workspace this morning to n8n@1.98.1, not sure if that is the problem.

What is the error message (if any)?

Definitely a bug, you can report it here. Or let me know if you don’t want to, I’ll do it for you.

Thanks, I’ve reported the bug

5

I’m getting the same error, any idea how to fix it?

6

It’s a bug. It has been reported and it’s being worked on. You can follow the progress here: PDF parsing broken in version 1.97.1 and up · Issue #16281 · n8n-io/n8n · GitHub

Same on v1.98.1 on Extract from PDF node – DOMMatrix is not defined.
FYI – convert to image and send to LLM for text.

8

Version 1.97.1 is working!

9

Same bug on 1.98.1

I think persist the bug…

11

facing the same problem on v1.98.1 on Extract from PDF node – DOMMatrix is not defined.

12

looks like there is a fix; need to wait to be incorporated to official.

13

This is the first time I’ve encountered a bug. Do you know how often this happens? How long does it take to fix it? Especially in the cloud version.

14

Rarely; check PDF parsing broken in version 1.97.1 and up · Issue #16281 · n8n-io/n8n · GitHub for updates and details why. As a temp measure convert pdf to image - might need PDF solution like self hosted stirling PDF and have cheap LLM like gemini 2.5flash-lite convert to markdown; you will get superior results esp PDF with graphics and tables.
