Hi @dosu, about langchain

[dosubot]

The first query successfully retrieves the lowest rating movies because it likely produces a correctly structured output that the output parser can handle. The second query results in an OutputParseError because the output parser encounters a parsing error, which is specifically handled by raising an OutputParserException. This exception indicates that the output from the second query is improperly structured or formatted in a way that the parser cannot process.

The RegexDictParser class in the LangChain framework provides a mechanism to parse the output of an LLM call into a dictionary using a regex pattern. If the output does not match the expected format, a ValueError is raised, which can lead to an OutputParserException if not handled properly ^[1][2][3].

In summary, the second query's output is not in the expected format, leading to the OutputParserException.

To continue talking to Dosu, mention @dosu.

Creative, but this issue doesn't follow our reuqired template or have a useful title. Going to close until there's a useful issue title and minimal code example
