When does this happen?

IF Using Python's @tool decorator with OllamaFunctions in create_tool_calling_agent results in a JSON serialization error during agent invocation.

How others solved it

THEN Ensure the language model supports native tool calling. For OllamaFunctions, use a model variant that supports function calling or switch to a model like OpenAI that has proven compatibility. Alternatively, manually bind tools using model.bind_tools() instead of using the agent constructor.

# Instead of create_tool_calling_agent, bind tools directly:
model = OllamaFunctions(model="mistral:7b-instruct-v0.3-q8_0", format="json")
model_with_tools = model.bind_tools(tools)
# Then use a RunnableLambda to invoke model_with_tools with a prompt including function definitions.
