When does this happen?

IF Model provider inconsistencies with tool-calling APIs when using certain pydantic schemas (e.g., Gemini fails on 'dob' field format).

How others solved it

THEN Implement an alternative mode that uses prompt engineering to guide the LLM to output JSON in its text response, then parse that JSON, bypassing tool-calling APIs. This ensures broader compatibility with models that struggle with tool-calling but can follow JSON schema prompts.
