The route receive a dict as input so you must change @app.route("/dashboard") to @app.route("/dashboard/<input>") and pass input to the route in the link of the route.

For example, I have a route as below.

@app.route('/user/<name>') def user(name): return render_template('home.html', name=name) To pass name to the route, I access the link http://localhost:5000/user/myname.
