Bitbucket Issue import fails

AbramA

I've setup a self hosted JIRA install and went to import existing projects from Bitbucket, which failed during the import. The project was created, but none of the issues were imported. Any trick to getting this to work?

Edit - Here's the import log:

I found that in there was an Add-On update for the JIRA Importer plugin. Updated that and re-imported project and most of the issues were imported without error. There were still a handful of issues that did not import becuase of errors - most were because of attachments or issues linked to other issues by issue #, but at least the updated importer plugin detailed each import error, and so I was able to manually recreate issues on my JIRA project.
