The class value passed back inside the trained model is empty

The problem is that the class name is empty in the json that roboflow sends back, and I went to check the project preview on the roboflow website. The class name is also empty. But when I train it, it is already commented. The images in the training set are also annotated.
I checked that I need to do class mapping, but I can’t find where to do this at that stage.

Hey @剑_杨

Could you share the endpoint that you are requesting from where you aren’t getting your desired response? (ex: Hosted Inference API, Versions, Project, etc)

Also, sending the full JSON response, which you say was missing the class value, here would also be very helpful
