Describe the problem/error/question
How can i use a respond to chat node? This is a simple workflow with respond to chat. However it seems to keep ‘waiting for input’
What is the error message (if any)?
None. just keep waiting for input. Even if i try to key in something at the chat, it still would not work.
Please share your workflow
