Unable to import cards from trello to jira

[Khiman Louër]

I am getting an unknown error from the log, with no details at all. Nothing is out of the ordinary, I imported another board yesterday already and it worked fine. What could be causing this?

Does anyone from the atlassian team have more verbose logs?

Hello @Khiman Louër

Welcome to the Atlassian Community!

Can you please provide us with the complete error message to better troubleshoot why your Trello import is returning the error? More specifically, what is returned after "Data may be in an unstable state:"?

There are a few bugs in the import client from Trello that might be causing your issue:

Trello import to JIRA fails due to Trello API Rate Limiting. 

Unable to import from Trello on JIRA Core (IndexOutOfBoundsException) 

Importing Trello board with assignee other than the admin causes IllegalStateException error 

Could you please take a look at the bugs above and check if you are being impacted by one of them?

If the bugs above did not match the error you are facing, please provide us with the full error description so we can further investigate the problem.

Let us know if you have any questions.

Hello, as I already said, there is nothing more to it. The error message I posted is what I'm getting, that's the end of the log.

I am currently trying to troublshoot this with David Ingty at JST-595810

Did you resolve this? I have a similar error. The last card mentioned by the import log isn't imported (despite being extremely simple - just one line in its description), and the last line of the import log is:

2021-09-12 18:20:28,508 ERROR - Unexpected failure occurred. Importer will stop immediately. Data may be in an unstable state:

It sounds as if there should be something further after this, but there is nothing.
