I can't refresh the upscalers list from the API

[julianpoma]

I have a server that is running the A1111 webui server and I use it to generate txt2img based on API requests. Some images may use upscalers, that I download on demand into the models/ESRGAN folder.

The problem that I am facing is that the upscaler is not recognized by the SD-webui unless I restart the server. If I don't do it, I get a Exception | | could not find upscaler named my_upscaler when i post to the txt2img endpoint.

Once I kill the SD-webui process and spawn it again, I can use this upscaler.

I checked the API docs, but I don't see an endpoint to refresh the upscaler lists, like there is with the VAE, Checkpoints, Loras. Is this not supported?

Thanks!
