chat_template not found

[TheFausap]

Hello,

when I try to submit a request using the api, I have an INTERNAL SERVER ERROR, and in the logs I can see:

ValueError: Cannot use chat template functions because tokenizer.chat_template is not set and no template argument was passed! For 
information about writing templates and setting the tokenizer.chat_template attribute, please see the documentation at 
https://huggingface.co/docs/transformers/main/en/chat_templating

The thing is the model has a tokenizer.chat_template set... so the error above makes no sense.
For example, if I run the following python code, it executes without problem

from mlx_lm import load, generate

model, tokenizer = load("fausap/Cydonia-24B-v4.1-4bit")

prompt = "hello"

print("Applying tokenizer template...")
messages = [{"role": "user", "content": prompt}]
prompt = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True
)

response = generate(model, tokenizer, prompt=prompt, verbose=True)

the output is

Applying tokenizer template...
