[BUG] Error while converting document to PDF: 404 Client Error: Not Found for url: http://gotenberg:3000/convert/office

[philippguertler]

Describe the bug When processing a .docx I got this error message:

Error while converting document to PDF: 404 Client Error: Not Found for url: http://gotenberg:3000/convert/office

To Reproduce Steps to reproduce the behavior:

1. Use this docker-compose file
2. Upload a file that is processed by gotenberg

Expected behavior I expected no error message

The issue is that gotenberg got a major update recently - version 7. This update included a change in the API.

The docker-compose files always use the latest version of gotenberg, now 7. Paperless-ng is not yet compatible with this version.

Using version 6 of gotenberg resolved the issue for me.

@philippguertler I've created a pull request to fix your issue here. If you find the time, it would be nice to check whether this resolves your issue or not. Please free to test with as much documents as you like. I only tested the new Gotenberg version with a few ones.

@Tooa - I want to test this, but am running docker on windows... is there nightly build off of master that I would be able to install? Would running one of these, or compiling my own, break anything or make upgrading to the next release more difficult, loose data, etc.?

[smseidl]

@Tooa - I think I was able to build the container from master and have it running (honestly not 100% sure how to confirm) and still got the error today for a new docx. Below is the error message and a screenshot of my docker desktop.

[smseidl]

My mistakes. I checked out master instead of dev, and didn't update my docker-compose.yaml to move from thecodingmachine to gotenberg. My first check now worked.

[almanzarj]

@smseidl did you have to add any special command on your docker-compose for gotenberg?

I added the below to gotenberg and still not working using image: gotenberg/gotenberg:7 and image: jonaswinkler/paperless-ng:dev

command:
  - "gotenberg"
  - "--chromium-disable-routes=true"

[kabili207]

I had to switch to image thecodingmachine/gotenberg:6 in order to get it to work. It looks like version 7 changed the conversion endpoint

[erm67]

gotenberg API has changed, see https://gotenberg.dev/docs/modules/libreoffice, editing parsers.py with the correct end point fixes the problem. It works for me, I converted 20 odt documents without problems.

I too was having this issue, changing image back to "6" resolved it!

Thanks @dafinga - just wanted to confirm this change worked fine for me! 👍

(NB. Just seen that dev is already up-to-date on this - lovely!)

[yieldhog]

@dcgsteve apologies if this is a dumb question, but, if I login to the docker container with bash, where is this file (parsers.py / parsers_7.py) located so I can modify? Thanks

[dcgsteve]

It's here :)

https://github.com/dcgsteve/paperless-ng/blob/7bc8325df910ab57ed07849a3ce49a3011ba55b6/src/paperless_tika/parsers.py#L67

[yieldhog]

Ah -- thank you figured it out and working! If anyone uses linuxserver image:

docker exec -it paperless-ng /bin/bash edit: /app/paperless/src/paperless_tika/parsers.py

[siancu]

If anybody else wants to try the change but doesn't want to build the image manually, I've uploaded it to siancu/paperless-ng. It has the change to the parsers.py file as well as the change in docker-compose.yml.

[tompsg-git]

I solved it with

PAPERLESS_TIKA_GOTENBERG_ENDPOINT: http://gotenberg:3000/forms/libreoffice/convert#
