How to send form data to MongoDB using Flask

Question

I'm a student and trying to make a simple image uploading API using form data and MongoDB. But I'm having hard time solving errors.

I think it's the server side that keeps making the problems but I really can't find what exactly is wrong.

@app.route("/insta_feed1", methods=["POST"])
def feed_post():
    file = request.form.get['file']
    image = request.form.get['image']
    content = request.form.get['content']
    user_id = request.form.get['user_id']
    doc = {'file': file, 'image': image, 'content': content, 'user_id': user_id}
    db.insta_feed1.insert_one(doc)
    return jsonify({'msg': 'image uploaded'})

I have files and contents appeded like this.
