As the link states, just add “Formatting re-enabled” as the very first thing in your prompt. And then follow that up with the rest of your prompt.

Are you sure? Maybe:

'messages' => [
                        [
                            "role" => "system", // developer ???
                            "content" => "Formatting re-enabled"
                        ],
                        [
                            "role" => "user",
                            "content" => $prompt
                        ],
                    ],
