SwarmUI "Creat New Presets" not work in Ubuntu22.04,,need help!

[superhighsky]

In ubuntu system, swarmui cannot use the "Creat New Presets" function, and there is no response after clicking "Creat New Presets",anyone know why?

• What browser?
• Does the modal for preset config pop up?
• is there any error in your browser's debug console (hit F12)?
• Is there any error in Swarm's logs (in the terminal window, or Server -> Logs in the UI)

Thank you so much for the help provided, it's amazing to try it many times today and actually work after restarting！！

You're somehow sending a generation with a preset that doesn't exist -- I pushed a commit to handle the error more cleanly
