Trouble Adding Subfield to Object in Set Node (New UI)

[Vishal]

Hi everyone,

I’m trying to build a WhatsApp automation in n8n Cloud (new UI) and am running into an issue with the Set node.

I’m following the correct structure to send replies via the WhatsApp API. As shown in the attached screenshot, I need to set the text field as an Object, and then add a subfield body of type String (containing the OpenAI output).

However, when I select Object from the type dropdown, the expected “Add Subfield” button or nested input panel does not appear.

Has anyone else experienced this? Am I missing a step or UI element?

Thanks in advance for any help!

New n8n version does not have subfield in set node. However, you can use dot notation with activating it from Option field.

I created one for you!

If it helps, kindly mark my message as solution, thanks!
