I'm trying to save the uploaded image like this: file.save(secure_filename(file.filename)) saving itself works, the picture appears, but if I add the return detect_faces_in_image(file) line below (result output), then the following error appears: builtins.OSError OSError: cannot identify image file how can i fix this?

ps the image is needed to add text to it and display it, maybe there is another way to do this?

@app.route('/', methods=['GET', 'POST'])
def upload_image():
  # Check if a valid image file was uploaded
  if request.method == 'POST':
    if 'file' not in request.files:
      return redirect(request.url)

    file = request.files['file']

    if file.filename == '':
      return redirect(request.url)

    if file and allowed_file(file.filename):
      file.save(secure_filename(file.filename)) // сохранение изображения
      # The image file seems valid! Detect faces and return the result.
      return detect_faces_in_image(file)
  

    
    
  # If no valid image file was uploaded, show the file upload form:
  return '''
  <!doctype html>
  <title>text</title>
  <h1>text</h1>
  <form method="POST" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" value="Upload">
  </form>
  '''
