Why is it when I upload a custom weight (YOLOv11n) it shows Oops something went wrong, there might be issues with this model

Oops something went wrong, there might be issues with this model

I am using a custom yolov11n model and I uploaded it, is there something I need to consider before uploading a custom weight? I trained it locally, with jupyter notebook and my own GPU, used best.pt

I also cannot see the metrics mAP, Precision and Recall. it just shows as blank
