I enabled TestRail - Youtrack integration plugin. It can connect to Youtrack, it can push new bugs to Youtrack, links to Youtrack are correct and working when I click on an issue ID.
However when I hover the mouse over a Youtrack issue ID I get the following error:
An Error Occurred Status missing for defect result of defect plugin "YouTrack".
What am I missing? How can I get a more detailed explanation of the issue?
