langchain moonshotChat exmaple didn't work

[newday1]

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from langchain_community.chat_models.moonshot import MoonshotChat
from langchain_core.messages import HumanMessage, SystemMessage
import os

Generate your api key from: https://platform.moonshot.cn/console/api-keys

os.environ["MOONSHOT_API_KEY"] = "xxxxx"

chat = MoonshotChat()

messages = [
SystemMessage(
content="You are a helpful assistant that translates English to French."
),
HumanMessage(
content="Translate this sentence from English to French. I love programming."
),
]

chat.invoke(messages)
