Attachment import fails

[nielsgeo]

Issue

To Deck imported attachment files are corrupted (.pdf, .docx) or contain text "unauthorized permission requested" instead of the Trello attachment content (.txt). Import of cards, comments, checklists works fine, no error messages, only "successfully migrated to deck!"

Seems as if links to attachments on trello servers are not accessible for trello-to-deck (as usual in browser if not logged in to trello). Maybe necessary to provide trello's login details to trello-to-deck?

To reproduce:

• Run the tool and import Trello-Board with attachments (.pdf, .docx, .txt)
• Check attachments in Deck after import

OS

Win10
Python 3.9.4

Nextcloud version

20.0.13 (most likely, it is a manged server I do not have access to)

Please feel free to ask for any details if needed. Thanks a lot for providing this essential tool!

Hm that could actually be! Did it the import work for images? I suppose trello handles images and other attachments differently.

Maybe this would be an API which could simplify this: https://developer.atlassian.com/cloud/trello/guides/rest-api/automating-exports/

Thanks for quick reply.
.jpg images are likewise not imported in correct way. Same content if I open with text editor.

Oke this is very strange, because it means that Trello changed their policy. Previously it was possible to download attachments without authentication

I'll soon have more free time (next week). In the mean time one option could be to make your board public for a short time.
