Hey there @deku0818! 🥳
I'm Dosu, a friendly bot designed to help you squash bugs, answer your queries and guide you towards contribution to the LangChain project. While we wait for a human maintainer to join us, I'm here to assist you with your issue. Let's make coding fun together! 🚀
Based on the error message you provided, it seems like the response object is a string when the _create_chat_result method is expecting it to be a dictionary. This is why you're seeing the AttributeError: 'str' object has no attribute 'dict'.
The _create_chat_result method is defined in the ChatOpenAI class in the base.py file. Here is the method:
def _create_chat_result(self, response: Union[dict, str]) -> ChatResult:
if isinstance(response, str):
response = json.loads(response)
response = response.dict()
return ChatResult(**response)As you can see, this method is expecting response to be either a dictionary or a string. If response is a string, it tries to convert it to a dictionary using json.loads(). However, if response is already a dictionary, it tries to call dict() on it, which is not valid and results in the error you're seeing.
To fix this issue, you could modify the _create_chat_result method to only call dict() on response if it's not already a dictionary. Here's how you could do that:
def _create_chat_result(self, response: Union[dict, str]) -> ChatResult:
if isinstance(response, str):
response = json.loads(response)
if not isinstance(response, dict):
response = response.dict()
return ChatResult(**response)This code checks if response is a string and converts it to a dictionary if it is. Then it checks if response is not a dictionary and tries to convert it to one if it's not. This should prevent the AttributeError from occurring.
Please try this solution and let me know if it works for you. If you're still having issues, please provide more details about your code and I'll be happy to help further.
For more information about the ChatOpenAI class and the _create_chat_result method, you can refer to the LangChain documentation.
You can also refer to the source code of the ChatOpenAI class in the LangChain repository: libs/core/langchain_core/language_models/chat_models.py
I hope this helps! If you have any other questions, feel free to ask.
Best regards, Dosu
