Java file requests invalid

API
1

Hey there!
I am having quite a bit of trouble sending an API call to POST https://api.openai.com/v1/audio/transcriptions

Here’s an example of my code:

// Create Temporary file
File tmpFile = Files.write(Path.of(Files.createTempDirectory("uploads_") + File.pathSeparator + fileName), fileData).toFile();
// Put the file in the body...
FileBody fileBody = new FileBody(tmpFile, ContentType.DEFAULT_BINARY);

// Build the multiPartFile
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addTextBody("model", model);
builder.addTextBody("language", languageCode);
builder.addPart("file", fileBody);

// Prepare Client
HttpClient httpclient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost("https://api.openai.com/v1/audio/transcriptions");

// Prepare Payload

httpPost.setEntity(builder.build());
// Set Headers
httpPost.addHeader(HttpHeaders.AUTHORIZATION, "Bearer " + this.apiKey);
httpPost.addHeader(HttpHeaders.CONTENT_TYPE, "application/json");

HttpResponse response = httpclient.execute(httpPost);
HttpEntity entity = response.getEntity();

Here’s the error I am getting ( It’s invalid JSON ):

java.lang.Exception: Invalid HTTP Response from API received: {
    "error": {
        "message": "We could not parse the JSON body of your request. (HINT: This likely means you aren't using your HTTP library correctly. The OpenAI API expects a JSON payload, but what was sent was not valid JSON. If you have trouble figuring out how to fix this, please send an email to support@openai.com and include any relevant code you'd like help with.)",
        "type": "invalid_request_error",
        "param": null,
        "code": null
    }
}

Hope somebody can help me out, I am more or less stuck on this, and the api is just saying it needs a JSON but also requesting a file? Sorry if this is coming off as noobish :sweat_smile:

In the line

httpPost.addHeader(HttpHeaders.CONTENT_TYPE, "application/json");

You are telling the application you will be sending json data, but you are actually sending multipart-form data. try replacing "application/json" with "multipart/form-data"
