I facing this error when uploading images in static blocks.

Can anyone suggest me, why is this happen?


Create the new module, Then add below code in your module di.xml


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Framework\App\Filesystem\DirectoryResolver"

Now Create the file,


and add below code in the file:


namespace Vendor\Mymodule\App\Filesystem\DirectoryResolver;

use Magento\Framework\App\Filesystem\DirectoryList;

 * Magento directories resolver.
class DirectoryResolver 
     * @var DirectoryList
    private $directoryList;

     * @param DirectoryList $directoryList
    public function __construct(DirectoryList $directoryList)
        $this->directoryList = $directoryList;

     * Validate path.
     * Gets real path for directory provided in parameters and compares it with specified root directory.
     * Will return TRUE if real path of provided value contains root directory path and FALSE if not.
     * Throws the \Magento\Framework\Exception\FileSystemException in case when directory path is absent
     * in Directories configuration.
     * @param string $path
     * @param string $directoryConfig
     * @return bool
     * @throws \Magento\Framework\Exception\FileSystemException
    public function validatePath($path, $directoryConfig = DirectoryList::MEDIA)
        $realPath = realpath($path);
         * Since media directory is a symlink, need to run both paths through realpath in order for the comparison to
         * work.
         * The proper fix for this should involve a STORE > Configuration setting where an admin can choose whether to
         * allow symlinked directories.
        $root = realpath($this->directoryList->getPath($directoryConfig));
        // END EDIT

        return strpos($realPath, $root) === 0;

Please create the require file for module registration.php and module.xml
