Fix OutputParserException

✅ Solution

The "OutputParserException" in ragas usually occurs when the LLM's output format doesn't match the expected format defined in the output parser (e.g., expecting "text" but receiving "statements"). To fix it, carefully review the output parser's expected format in the ragas metric definition (often a pydantic class) and adjust the LLM prompt instructions and output parsing logic to ensure the LLM consistently returns data in the required structure. Specifically handle cases where the intermediate output is incorrect and consider adding error handling to gracefully manage unexpected output formats and potential repair mechanisms.
