DW Q & A Error: count(): Parameter must be an array

DW Question and Answer is causing this error in my WordPress:

[28-Jan-2018 18:46:56 UTC] PHP Warning: count(): Parameter must be an array or an object that implements Countable in /xxx/xxxxxx/xxxxx/wp-content/plugins/dw-question-answer/inc/Status.php on line 247

The code that causes this error is in the Status.php file and it is here:

	$latest = get_transient( 'dwqa_latest_answer_for_' . $question_id );
	if ( false === $latest ) {
		$args = array(
			'post_type' 		=> 'dwqa-answer',
			'meta_query' 		=> array(
				array(
					'key' 		=> '_question',
					'value' 	=> $question_id,
					'compare' 	=> '=',
				),
			),
			'post_status'    	=> 'public,private',
	    	'numberposts' 		=> 1,
		);
		$recent_answers = wp_get_recent_posts( $args, OBJECT );
		if ( count( $recent_answers ) > 0 ) {
			$latest = $recent_answers[0];
			// This cache need to be update when new answer is added
			set_transient( 'dwqa_latest_answer_for_' . $question_id, $latest, 450 );
		}
	}

The error does not prevent the site from working, but generates a very large log in the root folder.

I solved my problem by commenting on these two lines.

// if ( count( $recent_answers ) > 0 ) {

//}

But this can be revised in the next updates of the plugin.
