Hi, are you using a merge node in that workflow? Could you please provide a clear screenshot of your workflow or directly share the workflow JSON here?
I have several workflows with complex merges, but this will depend on the output of the previous nodes. If I test it with just Set nodes, each having only one parameter output, it can run and take data from the initial node without a merge node.
If there’s a node that’s cutting off your workflow’s path, you can try bypassing it directly to the error node using a Merge node. It would be too complex for me to ask about the parameter types of all the nodes in your previous workflow.
Are you using a session system to adapt to different workflow concepts? If so, try connecting it with Typebot. It would be very useful for streamlining your session handling in a chat context.
