Hello,
Debug next code (system\Dispatcher\Standard.php)
try { $this->module = \IPS\Application\Module::get( $this->application->directory, \IPS\Request::i()->module, static::i()->controllerLocation ); } catch ( \OutOfRangeException $e ) { \IPS\Output::i()->jsFiles = array_merge( \IPS\Output::i()->jsFiles, \IPS\Output::i()->js( 'app.js' ) ); throw new \DomainException( 'requested_route_404', 6 ); }  

You should to use additional attributes
img[data-src]
[data-background-src]
iframe[data-embed-src]
video[data-video-embed]
+ controllers which support lazy load or attribute data-ipsLazyLoad
 
Examples
<div data-controller='core.front.core.lightboxedImages'> {{if settings.lazy_load_enabled}} <img src='{expression="\IPS\Text\Parser::blankImage()"}' data-src='link_to_img' alt="alt_text"> {{else}} <img src='link_to_img' alt="alt_text"> {{endif}} </div>  
<div data-ipsLazyLoad> {{if settings.lazy_load_enabled}} <img src='{expression="\IPS\Text\Parser::blankImage()"}' data-src='link_to_img' alt="alt_text"> {{else}} <img src='link_to_img' alt="alt_text"> {{endif}} </div>  

See template chooseCurrency
{{$memberCurrency = ( ( isset( $_SESSION['currency'] ) and in_array( $_SESSION['currency'], \IPS\nexus\Money::currencies() ) ) ? $_SESSION['currency'] : \IPS\nexus\Customer::loggedIn()->defaultCurrency() );}}
