• [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

Using a ConversationSummaryBufferMemory generates an error:

                chat_history_for_chain = ConversationSummaryBufferMemory(llm=self.model,
                    memory_key="history",
                    input_key="input",max_token_limit=200,
                   return_messages=False) 

             self.chain_with_message_history = RunnableWithMessageHistory(
            self.chain_with_chat_history,
            lambda session_id: chat_history_for_chain,
            input_messages_key="input",
            history_messages_key="history",
        )

The code works fine if replaced with another type of memory
