This is due to isset() function using in lib/Driver.php (v 1.22.2.6) in line
177:

if (isset($this->_tasks[$id]) &&
isset($this->_tasks[$id][strtolower($attribute)])) {

The issue can be resolved by replacing second isset() by array_key_exists()

if (isset($this->_tasks[$id]) && array_key_exists(strtolower($attribute),
$this->_tasks[$id])) {

After applying this patch all works fine.
