huggingchat/chat-ui · custom model not working

Hi,
I cloned chat-ui to my space. If I instantiate the MODEL var with the proposed model - -- it works. If I change it with sineglossa/Minerva-7B-instruct-v1.0 it does not. When I enter a prompt, I get back a "fetch failed" error. Here is the log. How could I develop a chatbot with Minerva model??
