Originally created by @ashburnham on GitHub (Nov 24, 2024).

I can't deploy my agent to langgraph platform, or run it locally via langchain studio, as when I try to it says @langchain/langgraph-sdk doesn't exist..

While debugging, it seems that this comes from a file that is part of the langgraph disk image that edits the imports for any package that starts with @langchain/langgraph. I think that code is there to catch @langchain/langgraph/foo/bar imports, but it's messing up @langchain/langgraph-sdk too...

This is an issue as I want to run background memory jobs like thsi

https://github.com/langchain-ai/memory-template-js/blob/main/src/chatbot/graph.ts

but I can't when I include @langchain/langgraph-sdk the build fails with the above error...

@ashburnham, is there a stack trace for the error you're seeing? If so, can you share the full stack trace and the exact error message?

I'm able to reproduce the error by deploying memory-template-js.

This still needs to be causing builds to fail?
