Session variables (called "conversation variables") are not supported in Dify workflows as of version 1.3.1—they are only available in Chatflow, not in workflows. This is by design, since workflows are intended for one-off tasks and do not maintain state across sessions. If you need to persist or reference user input across multiple steps in a workflow, you can use workflow variables (not session variables) and pass values between nodes using the variable assigner node. For persistent session-like behavior, consider building your logic in Chatflow instead of a workflow.

I tried in chatflow and I also can not find and add any session variable

[heathdutton]

To create conversation variables in a workflow:

1. Click the gear icon in the top-right of the workflow editor to open "Features"
2. Scroll down to Conversation Variables section
3. Click + Add Variable to create one
4. Set name and type

Then use the Variable Assigner node to write values to these variables. Reference them elsewhere with {{#conversation.your_variable_name#}}.

Does that solve it?

@heathdutton I don't find the "Features" button in workflow editor, here is my workflow whole windwo screeshot. @dosubot[bot] I tried to add the Variable Assign node in a chatflow. I also can not find any possible session variables I can choose.
