i get this error:

bug from here

actually list_base_models does not have default value,

you can ealisy find this question with this code
`from swarms import Agent
from swarms.prompts.tools import tool_sop_prompt

from swarm_models import OpenAIChat
from swarms_memory import ChromaDB
import subprocess
import os
from swarms.tools.base_tool import BaseTool

def terminal(
code: str,
):
"""
Run code in the terminal.

Args:
    code (str): The code to run in the terminal.

Returns:
    str: The output of the code.
"""
out = subprocess.run(
    code, shell=True, capture_output=True, text=True
).stdout
return str(out)

BaseTool(
tools=[terminal],
base_models=None,
tool_system_prompt=tool_sop_prompt(),
)`
