Chat nodes are broken in n8n 2.11.3

[Illia_Simenko]

I am trying to set up very simple echo workflow to test the internal chat feature, but I get the error "Problem in node ‘Chat‘
“Response Mode” in the chat trigger node must be set to “Using Response Nodes”. The thing is - there is no such setting anywhere in chat trigger node. The trigger node version is 1.4.

Here is my workflow:

Here is the error details:

Hello @Illia_Simenko

go within options > add field - here you can include the ‘Using Response Nodes’

Here’s a simple workflow that performs the activity using ‘Respond Chat’ node preferable over ‘Chat’ Node

Let us know how this goes for you - please mark comment as solution if this solves your issue.
