Hi there very new to huggingface and I am trying to run transformers agent however, I keep getting the error below. Any help on this would be greatly appreciated.

```auto
import os
from scripts.global_var import config

default_home = os.path.join(os.getcwd(), ".cache")
hf_cache_home = os.path.join(default_home, "huggingface")
os.environ["HF_HOME"] = hf_cache_home
os.environ["HF_TOKEN_PATH"] = os.path.join(hf_cache_home, "token")
from huggingface_hub import login

login(config["huggingface_api"])
from transformers import HfAgent

agent_star = HfAgent(
    "https://api-inference.huggingface.co/models/bigcode/starcoder"
)
text = "this is new building with 14 storeys painted green."
storey_1 = agent_star.run("What is the number of storeys?", text=text)

```

```auto

Please update the permissions of the token to write/read, which can solve the problem.
