You can see the$promptvalue in my application below. When I enter this prompt value, chat GPT gives no results. But this is because of"stream" => falsein the parameter. If"stream" => true, chat GPT gives the result.

My question is why chat GPT doesn't give results when"stream" => false. And what to do to produce results.
