我正在尝试使用Langchain-Openai创建一个聊天机器人。我之前从未做过这个。我创建了一个全新的API密钥，这个密钥之前从未使用过。我从官方langchain-openai文档中复制了代码，以下是代码：
from langchain_core.prompts import PromptTemplatefrom langchain_openai import OpenAIOPENAI_API_KEY = 'sk-proj-...'template = """Question: {question}Answer: Let's think step by step."""prompt = PromptTemplate.from_template(template)llm = OpenAI(openai_api_key="sk-proj-...")llm_chain = prompt | llmquestion = "What NFL team won the Super Bowl in the year Justin Beiber was born?"llm_chain.invoke(question)它显示了一个很长的错误信息：

所有的代码都来自Langchain-Openai文档。
我做错了什么吗？
编辑：正如@trazoM指出的，代码本身运行得很好，但显然我只需要创建一个新的密钥并关联一张信用卡。谢谢@trazoM！

正如@trazoM指出的，代码本身运行得很好，但显然我只需要创建一个新的密钥并关联一张信用卡。谢谢@trazoM！写下这些是为了让这个问题显示为已回答。
