    Any error generated by Haystack.

    This error wraps its source transparently in such a way that its attributes
    can be accessed directly: for example, if the original error has a `message` attribute,
    `HaystackError.message` will exist and have the expected content.
    If send_message_in_event is set to True (default), the message will be sent as part of a telemetry event reporting the error.
    The messages of errors that might contain user-specific information will not be sent, e.g., DocumentStoreError or OpenAIError.
