I was making a python script that uploads local pdf files to my wordpress website, using the wordpress api, but for some reason, the post method with media endpoint just gives me a lot of random data including other media files instead of uploading my pdf.

wp_credentials = f'{wp_user}:{wp_password}'
token = base64.b64encode(wp_credentials.encode())

wp_header = {
  'Authorization': 'Basic ' + token.decode('utf-8')
}

def upload_to_wordpress(file_path):
  media = {
    'file': open(file_path, 'rb'),
    'caption': f'invoice: {file_path}',
    'description': f'invoice: {file_path}'
  }

  pdf =  requests.post(wp_url, headers=wp_header, files=media)
  print(pdf)
  pdf_url = str(json.loads(pdf.content))

  print(pdf_url)
  return pdf_url

I tried following the documentation and many other tutorials, but I stumble upon the same problem each time.
It also gives me status [200] insetead of the intended [201].
