Uploading css and js from active rails admin in apache

Friends decided to post this question after much research and unsuccessful attempts. I am configuring a VPS, where in it, a site containing a administration section is being hosted. the Front eh in React and the Back in Ruby. The adm section was made with Ruby ActiveAdmin. Here's the problem: The site is running cool, but at the time of accessing / admin the css and js do not load. Here's my apache .conf file:

<VirtualHost *:443>
    ServerName meusite.com.br
    ProxyRequests off
    SSLEngine On
    DocumentRoot /var/www/meusite/build
    ErrorLog /var/www/meusite/log/error.log
    CustomLog /var/www/meusite/log/access.log combined
    SSLCertificateFile /etc/ssl/certs/meusite/meusite.crt
    SSLCertificateKeyFile /etc/ssl/certs/meusite/meusite.key

    <Directory /var/www/meusite/build>
        AllowOverride All
    </Directory>

    <Location /admin>
        ProxyPass http://localhost:3002/admin/
        ProxyPassReverse http://localhost:3002/admin/
    </Location>

    <Location /api>
        ProxyPass http://localhost:3002/
        ProxyPassReverse http://localhost:3002/
    </Location>
</VirtualHost>
