    # Here is an example middleware to add headers for qBittorrent support
    
    qBittorrent-headers:
      headers:
        content-security-policy: default-src 'self'; style-src 'self' 'unsafe-inline' theme-park.dev raw.githubusercontent.com use.fontawesome.com; img-src 'self' theme-park.dev raw.githubusercontent.com data:; script-src 'self' 'unsafe-inline'; object-src 'none'; form-action 'self'; frame-ancestors 'self'; font-src use.fontawesome.com;

content-security-policy should be contentSecurityPolicy. At least in traefik 2.10.
