How to get linked beans function in SuiteCRM - suitecrm

Question

I want to setup email notification in suitecrm. I have created the logic hook and email notification php file. However my issue is that when it reaches this line $GLOBALS['log']->fatal("Could not find the department NC was issued to: ". $bean->name); it throws the error message. But I'm not understanding as to why it throws the error message if me syntax is incorrect.
class nc_email_notification {
public function email_notification(&$bean, $events, $arguments){
/*define 'review_pending' as string constant */
/*Get sugar email engine*/
$email = new SugarPHPMailer();
$email->From = 'suitecrm#gmail.com';
$email->FromName ='SuiteCRM';
/*Get the Department NC was Issued to */
$dept_array= $bean->get_linked_beans('dept_department_nccas_nc_case','dept_Department_sugar');
if(count($dept_array)==0){
/*log error*/
$GLOBALS['log']->fatal("Could not find the department NC was issued to: ". $bean->name);
}else{
/* Get email of users within the Department NC is issued to */
$user_array = $dept_array[0]->get_linked_beans('dept_department_users','User');
if(count($user_array)==0){
/*log error*/
$GLOBALS['log']->fatal("Could not find Users within the department NC is issued to: ". $bean->name);
}else{
$address=getDepartmentUsersEmail($user_array);
}
/*Get the Department NC was raised by */
$raised_dept_array= $bean->get_linked_beans('dept_department_nccas_nc_case_1','dept_Department_sugar');
if(count($raised_dept_array)==0){
/*log error*/
$GLOBALS['log']->fatal("Could not find the department NC was raised by: ". $bean->name);
}else {
/*Get email of users within the Department NC is raised by*/
$raised_user_array = $raised_dept_array[0]->get_linked_beans('dept_department_users','User');
if(count($raised_user_array)==0){
/*log error*/
$GLOBALS['log']->fatal("Could not find Users within the department NC is raised by: ". $bean->name);
}
else {
$r_user_address = getDepartmentUsersEmail($raised_user_array);
}
}
/*Get the Quality Systems Department*/
//$qual_dept=$dept_array[0]->retrieve)by)string_fields(array('name' => 'Quality Systems' ));
//$qual_dept->load_relationship('dept_department_email_addresses_primary');

$rev_email = 'ramon#gmail.com';
/*Get NC Action for the NC Case*/

Unfortunately I know nothing about the name of your fields.
First check the 'dept_department_nccas_nc_case'(should be $field_name) and 'dept_Department_sugar'(should be $bean_name).
Also you can try to use load_relationship
