Error after running MONAI Label in QuPath

[hocdb-KMU-TMU]

I have try to run MonaiLabel Plugin qupath-extension-monailabel-0.3.1.jar in QuPath 0.4.3 by following the steps in
https://docs.nvidia.com/launchpad/ai/monai-label/latest/monai-pathology-step-02.html.


The server shows

Can some one tell me which part I get it wrong?

I re-run the MONAI server it seems ok now.
Please let me know if I need to delete this post.
Thank you.

We can just close..

The difference that made the server works are
Instead of starting the server by typing in terminal
monailabel start_server --app apps/pathology --studies datasets/

I start the server by typing in terminal
monailabel start_server --app apps/pathology --studies datasets/pathology/

Besides, I drag the image into QuPath instead of using Next sample/Patch in the MONAI Label in toolbar
