Crash when trying to export to PDF

[kalon33]

When trying to export to PDF, for example the "Features" document, it crashes:

I use the latest docker image, hackmdio/hackmd:2.4.2-cjk.

Thanks for your help.

[mic4ael]

It is happening to our deployment as well..

Hi @kalon33 , @mic4ael
Thanks for report the issue.

We'll release 2.4.3 soon to resolve this issue.

The quick way to fix this bug is to set QT_QPA_PLATFORM to empty.

version: "3"
services:
  database:
    image: postgres:11.6-alpine
    environment:
      - POSTGRES_USER=codimd
      - POSTGRES_PASSWORD=change_password
      - POSTGRES_DB=codimd
    volumes:
      - "database-data:/var/lib/postgresql/data"
    restart: always
  codimd:
    # you can use image or custom build below,
    # if you need CJK character with exported PDF files,
    # please change the image tag with `cjk` postfix version
    image: hackmdio/hackmd:2.4.2-cjk
    environment:
      - CMD_DOMAIN=192.168.5.229
      - CMD_URL_ADDPORT=true
      - CMD_DB_URL=postgres://codimd:change_password@database/codimd
      - CMD_USECDN=false
      - QT_QPA_PLATFORM=
    depends_on:
      - database
    ports:

    volumes:

Thanks for the workaround idea!

@a60814billy @mic4ael Hi,

It is working and I now have a PDF document generated. It that expected that checkboxes, HTML code, etc... are not interpreted in the final PDF document and appear as raw code?

Thanks for your help.

[2001db8]

We'll release 2.4.3 soon to resolve this issue.

Are you still planning on releasing 2.4.3 anytime soon?

[AVert]

thanks for workaround? but either links not working nor [TOC] not showed

[tchellomello]

Interesting, I'm hitting the error even with the workaround in place.
