Generate an image and use it as a wordpress featured image?

Hey guys, I have a custom node that connects to my self-hosted wordpress website to publish posts. It works fine for posting the title, content, and category. I also have an image generator node, and I want to use the image it generates as the featured image in the blog post. How can I do this?

I keep getting this error:

WordPress Post Publisher Failed!
The code in the function body raised the following error:

Unsupported data type for file /storage.googleapis.com/agenthub-public/uid-a5ZXrj5z57dwgvJtKkmiyJPLIsn2/KsHQjKzEkmmJuQdSXuqk7s/generated_image_hnbhhnGwTrRTo9RazczN9x.png

Hey @cassihl – Can you send over the link to the flow or email it at support@gumloop.com please?

Additionally, can you provide me editor acccess to the custom node please? You can add me as an editor by hovering over the node, clicking on “Share,” typing in my email (wasay@gumloop.com), and then selecting the three dots to make me an editor.
