What happened?

I have a discord bot that manages sd-webui-forge as well as textgen-webui.

I wanted to add a feature to 'unload image model', but apparently this endpoint does not actually do anything at all.

When I execute it from the API window, nothing appears in the cmd window and my system resources are perfectly unchanged.

Steps to reproduce the problem

1. Go to http://127.0.0.1:7860/docs
2. Go to [POST] sdapi_v1_unload_checkpoint
3. Click "Try it out"
4. Click "Execute"
5. Nothing happens

What should have happened?

The currently loaded image model should get unloaded

What browsers do you use to access the UI ?

Google Chrome
