This was a known bug: https://github.com/langchain-ai/langgraph/issues/6318

For this code to work I had to upgrade to langchain==1.0.5

!pip install langgraph langchain==1.0.5 langchain_openai==1.0.0

Reasons:
  • Probably link only (1):
  • Low length (1):
  • Has code block (-0.5):
  • Self-answer (0.5):
  • Low reputation (1):
