POST error when running tutorial on MONAI Label with QuPath

[vinhtien]

Dear,

Following this tutorial https://github.com/Project-MONAI/tutorials/blob/main/monailabel/monailabel_pathology_nuclei_segmentation_QuPath.ipynb

Until the step, clicking MONAI Label/Annotations..., I selected as mentioned in the tutorial and click OK.
Then I got a popup message with this error:

(POST http://127.0.0.1:8000/infer/wsi/segmentation_nuclei?output=asap&image=JP2K-33003-1) 500

It seems that the URL is not correct as if I look at the MONAI Label API via 127.0.0.1:8000, I did not see wsi as a model.
Does any body face this kind of issue?

Running manually via MONAI Label API got the same 500 error
