Whoops, looks like something went wrong.

1/1RuntimeException in DebugClassLoader.php line 251:The autoloader expected class "PrestaShop\PrestaShop\Core\Addon\AddonListFilterType" to be defined in file "/########/home/vendor/composer/../../src/Core/Addon/AddonListFilterType.php". The file was found but the class was not in it, the class name or namespace probably has a typo.
