Steps to reproduce

As shown in the figure, when I pass in the input variable (with only the 'a' variable inside), only the value of the 'a' variable is determined when creating the conversation. Continuing the conversation afterwards cannot change the value of the 'a' variable no matter what, which is something I don't want to see,
My current scenario is a conversational robot that needs to provide real-time strategic responses based on the current reception time and employee status. However, I do not want to lose the user's short-term memory as employee status is constantly changing
I have also reviewed previous issues and know that dify has a feature called "session variable", but I cannot assign this variable to it in any form as input. It cannot autonomously determine when updates are needed and why the content needs to be updated

✔️ Expected Behavior

There can be a variable that will be updated in the workflow as a conversation progresses in real-time, rather than being fixed only when the conversation is created

❌ Actual Behavior

@liuzixiao666 Hello there! I'm here to help you with any bugs, questions, or contributions you have for the Dify project. Let's work together to solve the issue you're experiencing.

I found some relevant discussions and issues that might help with your problem of updating input variables in real-time during a conversation session in Dify:

1. Similar Discussions:

   • In a multi-round conversation, when using a post request, how can I change the value of the input parameter after the second round? ^[1]
   • In preview chat, can I change the input parameters without restarting the chat conversation? ^[2]

2. Related Issues:

   • Input variables cannot be updated (Closed) ^[3]
     • This issue suggests using the VariableAssignerNode class and the update_conversation_variable function to handle updates. The VariableAssignerNode supports different write modes (OVER_WRITE, APPEND, CLEAR) to update variables.

To achieve real-time updates of input variables during a conversation, you can use Conversation Variables and the Variable Assigner node. This setup allows you to dynamically update variables as the conversation progresses, ensuring that information like employee status can be updated and accessed throughout the session ^[4][5].

I have checked with our dev team several times, we will remain this behavior. Sorry.

Is there no way to input variable parameters into the workflow in the conversation？
