the following code is suppose to upload selected file to local Flask server.
for some unknown reason the request.files is empty after pressing the submit button in the form. I have no clue of why the file path is not sent to the server..

Flask server's code

import os
from flask import Flask, flash, redirect, render_template, request, url_for
from werkzeug.utils import secure_filename
UPLOAD_FOLDER = 'C:UsersuserDesktopuploads'
ALLOWED_EXTENSIONS = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'])
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
def allowed_file(filename):
 return '.' in filename and 
 filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS 
@app.route('/uploader', methods=['GET', 'POST'])
def upload_file():
 if request.method == 'POST':
 # check if the post request has the file part
 if 'file' not in request.files:
 flash('No file part')
 return redirect(request.url)
 file = request.files['file']
# if user does not select file, browser also
# submit an empty part without filename
 if file.filename == '':
 flash('No selected file')
 return redirect(request.url)
 if file and allowed_file(file.filename):
 filename = secure_filename(file.filename)
 file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
 return render_template('index.html')
return render_template('index.html')


 if __name__ == '__main__':
 app.secret_key = 'super secret key'
 app.debug = True
 app.run()
 app.run(debug=True)

HTML form code

<form action="http://localhost:5000/uploader" method="POST" enctype="multipart/form-data">
 <input type="file" name="file" class="custom-file-container__custom 
 file__custom-file-input" id="customFile" accept="*" aria- 
 label="Choose File">
 <input type="hidden" name="MAX_FILE_SIZE" value="10485760"/>
 <input type="submit" value="Press to upload file!">
 </form>

the code goes into the first 'if' condition and stops as if no path was selected..
