View Source LangChain.LangChainError exception (LangChain v0.3.1)
Exception used for raising LangChain specific errors.
It stores the :message
. Passing an Ecto.Changeset with an error
converts the error into a string message.
raise LangChainError, changeset
raise LangChainError, "Message text"
raise LangChainError, type: "overloaded", message: "Message text"

:type
- A string code to make detecting and responding to specific errors easier. This may have values like "length" or "overloaded". The specific meaning of the type is dependent on the service or model.:message
- A string representation or explanation of the error.:original
- If a exception was caught and wrapped into a LangChainError, this may be the original message that was encountered.
