Apply if condition on the response

[Gouravdev]

Describe the problem/error/question

I want to apply the if condition on the node,

If set2 is not triggered or has an empty value, the Merge item b should be the value of propertyName.

{{$node["Set2"].json["Hello"] ? $node["Set2"].json["Hello"] : $node["Merge"].json["b"]}}

What is the error message (if any)?

Please share your workflow

Share the output returned by the last node

hello @Gouravdev

You can’t reference nodes which haven’t been executed. Instead you can combine two different branches into one place and refer to it later
