I'm working with a set of Less CSS files I didn't write in Magento 2. During compilation, I get the following error
Compilation from source: frontend/Infortis/base/en_US/css/custom.less Compilation from source: frontend/Infortis/base/en_US/css/custom.less> #0 /path/to/magento/framework/View/Asset/PreProcessor/AlternativeSource.php(155): Magento\Framework\Css\PreProcessor\Adapter\Less\Processor->processContent(Object(Magento\Framework\View\Asset\File))
I know I can start debugging from line 155 in
AlternativeSource.php -- but does anyone know what this cryptic error means?
