Why can't I set up this virtual host?

cat  /etc/hosts
127.0.0.1  hwy.local  www.hwy.local  test.app   www.test.app

cat / etc/apache2/sites-available/000-default.conf

<VirtualHost *:80>
    ServerName www.hwy.local
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html
    ErrorLog ${APACHE_LOG_DIR}/error_hwy.log
    CustomLog ${APACHE_LOG_DIR}/access_hwy.log combined
        <Directory /var/www/html>
            Options Indexes FollowSymLinks MultiViews
            AllowOverride None
            Order allow,deny
            allow from all
        </Directory>
</VirtualHost>

<VirtualHost *:80>
ServerName www.test.app
ServerAdmin webmaster@localhost
DocumentRoot  /home/debian9/app
ErrorLog ${APACHE_LOG_DIR}/error_app.log
CustomLog ${APACHE_LOG_DIR}/access_app.log combined
    <Directory /home/debian9/app>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

File system

 touch  /var/log/apache2/error_hwy.log
 touch  /var/log/apache2/access_hwy.log
 touch  /var/log/apache2/error_app.log
 touch  /var/log/apache2/access_app.log
 sudo chown -R www-data:www-data /home/debian9/app
 sudo chmod -R g+rw /home/debian9/app
 sudo systemctl restart  apache2

Save the test file test.html in / var/www/html and / home/debian9/app .

it is a test

www.hwy.local/test.html opens normally.

curl -i  www.test.app/test.html
