AttributeError: 'NoneType' object has no attribute 'endswith'

I probably run out of memory or something is wrong with loading
the Q3_K_S model on my laptop with 16GB RAM and 6GB VRAM

model = AutoModelForCausalLM.from_pretrained(
        repo_id,
        gguf_file=filename,
        trust_remote_code=True,
        device_map="auto",
        use_cache=True,
        max_memory={"cpu": f"{ram:.2f}GiB", 0: f"{vram:.2f}GiB"},
        torch_dtype=torch.float
    )

   4358     )
-> 4359     is_safetensors = archive_file.endswith(".safetensors")
   4360     if offload_folder is None and not is_safetensors:

   4364             " offers the weights in this format."

Any idea?
