Dify version

1.6.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

my code，Call the app in the extension plugin, and the conversation_id will be used when there is a historical conversation.

response = self.session.app.chat.invoke(
                    app_id=plugin_settings.agent_app_id,
                    inputs=inputs_param,
                    query=robot_event.event_data.notify,
                    response_mode="blocking",
                    conversation_id= "" if memory is None else memory.conversation_id
                )

It works properly during remote debugging (INSTALL_METHOD=remote), but fails to execute chat.invoke when running the plugin in a Docker container on the server. The error message is as follows:

Traceback (most recent call last):
  File "/app/storage/cwd/wangfeng/popo_open_platform-1.0.7@1adf51af55a56aa1095ec0131cfafe1b5fe80dba28b81da24636765956ba9347/endpoints/popo_application_bot_callback.py", line 203, in call_agent
    response = self.session.app.chat.invoke(

    raise Exception("invocation exited without response")
Exception: invocation exited without response

✔️ Expected Behavior

When using self.session.app.chat.invoke in the plugin, it is expected that the passed conversation_id will work properly.

❌ Actual Behavior

No response
