Hello @gsans,
I'm here to assist you with your issue. It seems like you're encountering a TypeError when trying to implement the getting started code for chatModel from the LangChainJS documentation.
The error you're seeing typically occurs when you're trying to access a property of an object that hasn't been defined. In your case, it seems like the 'message' property of the 'generations[0][0]' object is undefined.
Looking at your network response, it seems like the response structure is slightly different from what the call method in base.js expects. The call method tries to access the 'message' property of the first item in the 'generations' array. However, in your network response, the 'message' property is nested inside the 'choices' array, which is not being accessed in the call method.
Here's the relevant part of your network response:
"choices": [
{
"index": 0,
"message": {
"role": "assistant",
"content": "Rainbow Steps Socks Co."
},
"finish_reason": "stop"
}
]And here's the relevant part of the call method:
const generations = result.generations;
return generations[0][0].message;As you can see, the call method is trying to access 'message' directly from the first item in the 'generations' array, but in your network response, 'message' is nested inside the 'choices' array.
To fix this issue, you might need to adjust the call method to correctly access the 'message' property from the network response. Here's an example of how you could do this:
const generations = result.generations;
return generations[0][0].choices[0].message;Please note that this is just a suggestion and might not work depending on the exact structure of your 'generations' array and the rest of your code. If you're still having trouble, please provide more context or details about the error.
I hope this helps! If you have any more questions, feel free to ask.
Best, Dosu

Following the code here.
The output is:
Looking at "base.js"
Not sure how to proceed as this is failing after adding the code from the docs.
Respone from Network looks good
