I found weird exception while investigating why ephemeral nodes were not removed for a long time:

: KeeperException("Transaction failed", exception_code),
          requests(requests_), responses(responses_), failed_op_index(getFailedOpIndex(exception_code, responses))
{
    addMessage("Op #" + std::to_string(failed_op_index) + ", path: " + getPathForFirstFailedOp());
}
std::string KeeperMultiException::getPathForFirstFailedOp() const
{
    return requests[failed_op_index]->getPath();
}
void KeeperMultiException::check(
    Coordination::Error exception_code, const Coordination::Requests & requests, const Coordination::Responses & responses)
{
    if (exception_code == Coordination::Error::ZOK)
        return;
    if (Coordination::isUserError(exception_code))
        throw KeeperMultiException(exception_code, requests, responses);
    else
        throw KeeperException(exception_code);
}
