This is not an issue, just wanted to say thank you! 3 years since last update and this still works and is very useful when you have relationships defined right in your issues graph!
First let me say thanks for making this - it looks super valuable.
I am trying to connect my YouTrack cloud instance and I'm getting this error once I hit "Connect". Is this fixable, or has the project not been updated to support the latest version of YouTrack or something?
