Producing an error reported on a different input key may mean that your escaping is not correct for JSON within JSON. Or that the batch API can’t handle things like characters of $ref – or sending response_format at all.

Report back: does removing the images from message content work, or do you get other errors with the response_format as sent?

Does your API request line sent as JSON bytes to the chat completions endpoint work?
