This exists to differentiate parsing errors from other code or execution errors that also may arise inside the output parser. `OutputParserException` will be available to catch and handle in ways to fix the parsing error, while other errors will be raised.

Args: error: The error that's being re-raised or an error message. observation: String explanation of error which can be passed to a model to try and remediate the issue. llm_output: String model output which is error-ing. send_to_llm: Whether to send the observation and llm_output back to an Agent after an `OutputParserException` has been raised. This gives the underlying model driving the agent the context that the previous output was improperly structured, in the hopes that it will update the output to the correct format. Raises: ValueError: If `send_to_llm` is `True` but either observation or `llm_output` are not provided. message error_codeNzLArguments 'observation' & 'llm_output' are required if 'send_to_llm' is True) isinstancestrcreate_message ErrorCodeOUTPUT_PARSING_FAILUREsuper__init__ ValueErrorrrr)selfrrrrmsg __class__s rr&OutputParserException.__init__sj4 eS ! !")*J*JE  K/:3E9 S/ !&$&r)rrr)NNF) r r r r rrr!boolr&r __classcell__)r*s@rrrsK#'!%!

Subclasses correspond to conditions that model providers report consistently, keyed to the HTTP status they surface it with, so the same condition maps to the same exception type regardless of provider. Provider integrations raise subclasses that also inherit from the provider SDK's own exception type, so code catching either continues to work.
