Unable to post when using a blob audio for talk

I am saving some audio files as blob in the db, but I am unable to post using the API

audio_url: "blob:https://localhost:3000/5d7e2c4a-4dd9-40be-8bde-8c59c114c6c7"

Code:


 const options = {  
      method: "POST",  
      url: "https://api.d-id.com/talks",  
      headers: {  
        accept: "application/json",  
        "content-type": "application/json",  
        authorization: API_KEY,  
      },  
      data: {  
        script: {  
          type: "audio",  
          audio_url: audioURL,  
        },  
        config: { fluent: "false", pad_audio: "0.0" },  
        source_url: img_url,  
      },  
    };

axios
  .request(options)
  .then(function (response) {
    console.log(response.data);
    setclipId(response.data.id);
  })
  .catch(function (error) {
    console.error(error);
  });

The response I get is:

"description": "validation failed",
