Answer 1

The exception handler for the actual error is failing. It expects a previous exception, but there is none.

The actual error is the exec method being disabled by php.ini disabled_functions.

        $disabled = explode(',', str_replace(' ', ',', ini_get('disable_functions')));
        if (in_array('exec', $disabled)) {
            throw new Exception\LocalizedException(new \Magento\Framework\Phrase('The exec function is disabled.'));
        }
