FileNotFoundError: Can't resolve url, neither hostname or project_dir passed

Hello,
I set up the label studio via python (conda) on windows 10.
I try to add label studio ml backend (using docker) , using the example mmdetection.
I added it properly in UI, the server is started.
But I get an error that i don t know how to solve.
Can someone please help me to solve it?
My image are actually in this folder: `C:\Users\user1\AppData\Local\label-studio\label-studio\media`

`FileNotFoundError: Can't resolve url, neither hostname or project_dir passed: /data/upload/3/`
