card.json missing (compose, powershell)

I got this error when I try to backup my trello.

I'm using docker-compose:

version: '2'
services:
  trello:
    image: trello_bck
    build: .
    volumes:
      - ./backups:/app
    environment:
      - TRELLO_API_KEY=1234
      - TRELLO_TOKEN=5678

And a powershell script to run the backups with a scheduler (work in progress):

# Script to automatically save trello

Set-ExecutionPolicy Unrestricted

Set-Location -Path $pwd

docker-compose up
docker-compose down

Several files are written on disk, and they have content. eg:

me/my_board/my_board_full.json me/my_board/0_list/0_card/card.json me/my_board/0_list/0_card/description.json me/my_board/0_list/0_card/attachments/the_attachments_are_ok

Any idea? thanks

Thanks for reporting the error, but I couldn't reproduce on Linux. Do you get the same issue without using the powershell script (docker-compose up --build)?

[dbonattoj]

Yes exactly the same problem.

I've also tried to put everything in C:/Users/user/document/project (user space) instead of D:/project and the docker client is well configured to have access to them.

But this does not change anything.

The folders/files created are approximately like this: tree /f > tree.txt

Every "card.json" is there UNTIL a card with a very long name:

How to make a good schedule ? when to study again/test ourself ? What is a practical way of doing so, using memory cards? direct from the book?

When I check the created folders I have:

2How to make a good schedule when to study againtest ourself What is a practical way of doing

WITH this symbol: "" And this folder is effectively empty. I think the problem is there.

I had the same problem previously with the how to use trello for android board, which I deleted.

EDIT: I have successfully backed up my trello by splitting this card, however the bug should be removed. I think that the "sanitize_file_name" function is not bullet proof. Another idea is to let the user the possibility to make folders following the shortlink or the id of the card. It is easier to use in other scripts.

Best regards,

The long name seems to be the root of the issue indeed. The sanitize_file_name function can be fixed. Otherwise PR #9 will help with the support of short links.
