[Bug] Unknown agent error: NotImplementedError: The delete_by_mark method is not implemented in AgentScopeSessionHistoryMemory class.

agentscope版本：1.0.13
agentscope-runtime版本：1.0.5

from agentscope_runtime.adapters.agentscope.memory import AgentScopeSessionHistoryMemory会触发agentscope报错：

agentscope从1.0.2版本新增delete_by_mark方法

Since service modules are deprecated, it is recommended to use the modules provided by AgentScope, for example:

# -*- coding: utf-8 -*-
import os

from agentscope.agent import ReActAgent
from agentscope.model import DashScopeChatModel
from agentscope.formatter import DashScopeChatFormatter
from agentscope.tool import Toolkit, execute_python_code
from agentscope.pipeline import stream_printing_messages
from agentscope.memory import InMemoryMemory
from agentscope.session import JSONSession


from agentscope_runtime.engine.app import AgentApp
from agentscope_runtime.engine.schemas.agent_schemas import AgentRequest

agent_app = AgentApp(
    app_name="Friday",
    app_description="A helpful assistant",
)


@agent_app.init
async def init_func(self):
    self.session = JSONSession(save_dir="./sessions") # Use JSONSession here


@agent_app.query(framework="agentscope")
async def query_func(
    self,
    msgs,
    request: AgentRequest = None,
    **kwargs,
):
    assert kwargs is not None, "kwargs is Required for query_func"
    session_id = request.session_id
    user_id = request.user_id

    toolkit = Toolkit()
    toolkit.register_tool_function(execute_python_code)

    agent = ReActAgent(
        name="Friday",
        model=DashScopeChatModel(
            "qwen-turbo",
            api_key=os.getenv("DASHSCOPE_API_KEY"),
            enable_thinking=True,
            stream=True,
        ),
        sys_prompt="You're a helpful assistant named Friday.",
        toolkit=toolkit,
        memory=InMemoryMemory(),  # Use InMemoryMemory() directly
        formatter=DashScopeChatFormatter(),
    )

    await self.session.load_session_state(session_id=session_id, agent=agent)

    async for msg, last in stream_printing_messages(
        agents=[agent],
        coroutine_task=agent(msgs),
    ):
        yield msg, last

    await self.session.save_session_state(session_id=session_id, agent=agent)


agent_app.run()

Or you can downgrade AgentScope to v1.0.11 or lower

See this release: https://github.com/agentscope-ai/agentscope-runtime/releases/tag/v1.0.5.post1
