Assistants API via shortcuts get contents

[wraith ingot]

I'm trying to access the Chatgpt assistants api and have everything up until this error code I'm getting. I've tried asking chatgpt but it just says to make sure everything is formatted corerctly. It's saying I need to have the asst id in there but i do so just trying to figure out how to make this work

you are passing all that as a single unnamed json key

so wrong body type

So how would I correct it?

change the request body from the menu or add every key from the value as own json key just like you did with headers
