When does this happen?

IF Using OllamaFunctions with function binding causes a KeyError: 'tool' because the model occasionally returns a dictionary with keys 'thoughts' and 'command' instead of 'tool' and 'tool_input'.

How others solved it

THEN Upgrade langchain-experimental to a version that includes PR #22339, which fixes the parsing inconsistency. In the meantime, install directly from the LangChain source: pip install git+https://github.com/langchain-ai/langchain.git#egg=langchain-experimental&subdirectory=libs/experimental.

from langchain_experimental.llms.ollama_functions import OllamaFunctions
# Workaround: patch _generate to handle both key formats or update library.
