      Original Description

      This happens on a Trello board that i have been able to import 4 weeks ago. I have looked at the new trello cards and archived cards but can not find anything strange. I have tried it in 3 different cloud instances with the same outcome. I also tried it on server+agile 6:latest but with no luck.

      Other boards are imported just fine, i also tried to create a board where i reproduce some of the cards that are in the board i can not import, such as huge checklists, using markup, unreachable attachments and so forth but without any luck.

      Plugin version is whatever is distributed in Jira Cloud.

      Can you please advise this is a big stopper for us as im supposed to import this board for a sprint on monday.

      Error log is attached to the issue
      Thanks
