Dynamically Pass an Array of Images in JSON to Claude or OpenAI Vision

The generated json ist valid, like i tested it online. I cant debug it, because i dont see the request Make does to Claude.

I have tried it with the JSON Modul, but my research hit me to do it this way.

because i need to generate it dynamic, based on the amount of the uploaded images.

Is it possible that i cant map value like a API call?
