wordpress querry.php is not working properlly

hello friends, i am try to execute one query in wordpress but it is giving me an error.

here is my code.

$jobs_args = array(     'post_type' => 'job',
		        'posts_per_page' => 10,
		        'paged'		=> $job_paged,
			'author'	=> array ( '6' ,'10'),
			 'post_status' => array( 'publish', 'pending', 'draft' ),
			);

			$jobs = new WP_Query( $jobs_args );

it is giving me warning like this “Warning: urldecode() expects parameter 1 to be string, array given in E:\Project\JobPortal\wordpress\wp-includes\query.php on line 2756
Call Stack”

also i checked the query is it coming like this

"ELECT SQL_CALC_FOUND_ROWS  wpjb_posts.ID FROM wpjb_posts  WHERE 1=1  AND wpjb_posts.post_author NOT IN (0)  AND wpjb_posts.post_type = 'job' AND ((wpjb_posts.post_status = 'publish' OR wpjb_posts.post_status = 'draft' OR wpjb_posts.post_status = 'pending'))  ORDER BY wpjb_posts.post_date DESC LIMIT 0, 10"
