Api call return empty, but works in playground

Hi, any can tell me why this return empty text

{"prompt":"summarises: Quantity: Each package weighs around 500 g and the stone is approximately 160-200 pieces. Size: 8-12 mm, oval shape.

I have made a script that works with curl and reads a csv and sends it to the api. And it returns the empty text.
But if I paste this same text with the same configuration and paste it in the playground it works.
This example works with text-babbage-001


Hi @srnatan

Welcome to the OpenAI community.

Sharing the complete script and API response will be very helpful.

  $engine = "text-babbage-001";
  $url = "https://api.openai.com/v1/engines/$engine/completions";
  $authorization = "Authorization: Bearer $OPENAI_API_KEY";

  $clean_text= str_replace(["\n","\r"],"",$tex);

  $data = array(  "prompt" => "$clean_text",
                  "temperature" => floatval($temperature),
                  "max_tokens"=> intval($len),
                  "top_p" => 1,
                  "frequency_penalty" => 0,
                  "presence_penalty" => 0

  $postdata = json_encode($data);

  $ch = curl_init($url);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization ));
  $result = curl_exec($ch);

And response is

{"id": "cmpl-54VANVDuu0zSBHRgYX4PA0Vaszc5T", "object": "text_completion", "created": 1651754799, "model": "text-babbage:001", "choices": [{"text": "", "index": 0, "logprobs": null, "finish_reason": "stop"}]}

Try to append a whitespace end of the text. Probably the engine is already assuming it has reached the end of the text.


OMG Thank you. With a whitespace at the end, all requests return text. It was driving me crazy


I found this question searching for “empty JSON”.

I had a different solution: my prompt string contained a single-quote and I had to escape it.
