when i try to configurate my image gen under the admin image settings i get the error ""GET /images/api/v1/models HTTP/1.1" 400 Bad Request" in the logs and "Something went wrong :/ Expecting value: line 1 column 1 (char 0)" in the web ui. My comfyui workflow works perfect

I also tryed with standart ComfyUI workflow - still get this error

The problem persists with comfyUI 0.2 and the latest 0.2.1

Also tryed a fresh install of open webUI
