Fix ValidationError

in RAGAS

Solution

ValidationError in Ragas often arises when the output format of your language model (LLM) doesn't match the expected schema defined by a metric or Ragas component, like expecting "text" but receiving a JSON object. To fix this, carefully inspect the output schema expected by the failing component in the Ragas documentation or source code and adjust your LLM prompt to strictly adhere to that format, ensuring it returns the precise data structure and field names. If parsing JSON, ensure it is valid and decodable.
