hi @mdism

I think you have to add an explicit dependency: langchain-core>=1.1.0 to the dependencies array

Hello **pawel-twardziak,

Thanks for the reply.**

Yes you are right, I added it explicetly while debugging the issue.

Anywhys the issue got resolved.

Actully, i noticed that I was facing the same whenever i use langchain or langgraph.

So, i though that might be the issue heppens while installing packges and intedepencies.

So, I reinstalled everything use –no-cache flag and after that its stared working without any error.

silly me. :blush:

Thanks,

Ismail
