hello, I had already spend two day working on this api, and I don’t know why that I can’t work on my side, I use Node.js create a ESMODULE server, and use fetch to upload the file.
I had try every thing I can and I record a video about what I currently stuck on,
I can upload the file , and I’m sure that I upload the correct file to the server, but the result is not what I expected, pls take a look and leave some common, thanks!

ps: the mp3 file I use in the video works fine when I manually use it on rapidapi, but I can’t use it neither “upload in javscript” or use “localPath in NodeJS”
