Content Filter not working (JS)

Hi, I’m trying to do the content-filter and I get an error. Im using the code implemented by @ali.yeysides in the comment above. When I try to implemented I get:

createError.js:16 Uncaught (in promise) Error: Request failed with status code 400

Im fust calling the function with a basic string:

  const contentFilter = async (prompt)  => {
    const toxic_threshold = -0.355;
    const wrappedPrompt = `<|endoftext|>${prompt}\n--\nLabel:`;
    const response = await openai.createCompletion("content-filter-alpha", {
      prompt: wrappedPrompt,
      temperature: 0,
      max_tokens: 1,
      top_p: 0,
      logprobs: 10,
    });
  
    let output_label = response.data.choices[0].text;
  
    if (output_label == "2") {
      const logprobs = response.data.choices[0]["logprobs"]["top_logprobs"][0];
  
      if (logprobs["2"] < toxic_threshold) {
        const logprob_0 = logprobs["0"];
        const logprob_1 = logprobs["1"];
  
        if (logprob_0 && logprob_1) {
          if (logprob_0 >= logprob_1) {
            output_label = "0";
          } else {
            output_label = "1";
          }
        } 
  
        if (logprob_0 && !logprob_1) {
          output_label = "0";
        }
  
        if (!logprob_0 && logprob_1){
          output_label = "1";
        }
      }
    }
  
    if (!["0", "1", "2"].includes(output_label)) {
      output_label = "2";
    }
  
    return output_label;
  }

try {
  contentFilter("Your content here")
} catch (error) {
  console.log(error)
}
