I will have a look in the next few days. |
…mpatible with previous versions.

Github build workflow seems to be not working, got this message in email: Error Seems like get-changed-files workflow step is not allowed? |

so it looks like we are making big changes to accomodate a new version of langchain. Sounds good but we keep making bug fixes for this version, so it may be best to have a fork where we determine what version of langchain we are using or we're going to have to maintain 2 versions of this package mapping to langchain versions |

@joseph-klein Is it possible to be backward compatible with LangChain < 1.0? |
|
Hi @YouNeedCryDear
Well I am going back and forth on that. At first I thought no, because langgraph has replaced "create_react_agent" with "create_agent" - the create_react_agent call is gone.
But just now I realized - langchain-oracle does not have any dependency on langgraph - its just langchain. So I think maybe it is ok.
Here is what I'll do: I will change the dependencies in the PR back so that we can use langchain 0.3 or 1.0.0, then I will test it against our AIDP agent flows and see if the existing flows that use older langchain stuff still works.

Hi @streamnsight,
Actually the big changes in oci-generative-ai.py are not related to the langgraph upgrade, they are just bugs we found when running AIDP agent flows, and I decided to combine into one PR. For now in AIDP itself we are using a forked version of that python file.
If you think they should be 2 different PRs I can split them up.
I will do the backward compatibility testing first. I guess if the langgraph version upgrade is backward compatible with the previous oci-langchain, then maybe its ok to combine them.
If it is not backward compatible, then I agree, maybe we should make a whole new github repo for "langchain-oracle-1.0.0" or something like that, and I'll add the bug fixes to both.
Thanks,
Joe
