Export failed

Error when I try to export

Notice: Undefined variable: post_ids_actual in …/wp-content/plugins/wp-csv/CPK_WPCSV_Engine.php on line 89

Catchable fatal error: Argument 1 passed to CPK_WPCSV_Export_Queue_Model::mark_done() must be of the type array, null given, called in …/wp-content/plugins/wp-csv/CPK_WPCSV_Engine.php on line 89 and defined in …/wp-content/plugins/wp-csv/CPK_WPCSV_Export_Queue_Model.php on line 74

Has worked in the past but not now – may be as the number of posts is too many now?
