Unable to import cards from trello to jira

Question

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?

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.

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.
