FLASK | Why do I get a 404 error after uploading a file?

I upload a file, the download information is displayed in the console, the file is uploaded - I get a 404 error.

<html>
<head>
  <title>Upload</title>
</head>
<body>
<form method=POST enctype=multipart/form-data action="{{ url_for('upload') }}">
    <input type=file name=photo>
    <input type="submit">
</form>
</body>
</html>

from flask import Flask, render_template, request
from flask.ext.uploads import UploadSet, configure_uploads, IMAGES

app = Flask(__name__)

photos = UploadSet('photos', IMAGES)

app.config['UPLOADED_PHOTOS_DEST'] = 'static/img'
configure_uploads(app, photos)

@app.route('/upload', methods=['GET', 'POST'])
def upload():
    if request.method == 'POST' and 'photo' in request.files:
        filename = photos.save(request.files['photo'])
        return filename
    return render_template('upload.html')


if __name__ == '__main__':
  app.run(debug=True)

remove action="{{ url_for('upload') }}"so that after loading it does not look for a new path, but simply receives a response with the file name in this form, return str(filename)
or remove the response altogether after saving the file and let the page reload
