Failure when importing a project from FogBugz

I tried importing a small FogBugz project (with 24 cases).
After some hours, GiLab indicated it Failed, however I can still see the project page.
I found that it imported 22 issues from a total of 24, but I found no information about the failure. I searched for some kind of log with some detail about the failure to not avail.

  1. Has anyone ran into this issue and found a solution/workaround?
  2. Is there any way I can check for error details?
