When does this happen?
IF When using OllamaFunctions with create_openai_functions_agent in LangChain, the agent executor fails with 'ValueError: Received unsupported message type for Ollama' due to internal message type conversion issues.
How others solved it
THEN Upgrade to a LangChain version that includes PR #22339 (merged but not yet released at issue time). As a temporary workaround, install langchain-experimental directly from the GitHub source by running: pip install git+https://github.com/langchain-ai/langchain.git#egg=langchain-experimental&subdirectory=libs/experimental. This should resolve the message type incompatibility and restore agent functionality.
pip install git+https://github.com/langchain-ai/langchain.git#egg=langchain-experimental&subdirectory=libs/experimental
