[X] I added a very descriptive title to this issue.
[X] I searched the LangChain documentation with the integrated search.
[X] I used the GitHub search to find a similar question and didn't find it.
[X] I am sure that this is a bug in LangChain rather than my code.
[X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
Example Code
from langchain.chains.openai_functions.openapi import get_openapi_chain
chain = get_openapi_chain("http://localhost:8080/v3/api-docs", llm=llm, verbose=True)
result = chain(question)
Error Message and Stack Trace (if applicable)
No response
Description
I am using openapi functions of langchain so that LLM can invoke appropriate endpoint given OpenAPI 3.0 spec documentation. I had observed that for a POST endpoint if the request body contains a Reference to an object then the schema of the object is not sent to LLM and hence LLM creates incorrect payload.
Below is an example Open API spec where-in the POST endpoint /pet has a request body with reference to Pet
Issue is specially for 'address' and 'hobbies' attribute shown in below schema
