What is causing "Object of class stdClass could not be converted to string"

Question

I'm receiving the following error:

Recoverable fatal error: Object of class stdClass could not be converted to string in DatabaseStatementBase->execute() (line 2227 of includes/database/database.inc).

I've narrowed it down to this code but I am still able see what is wrong with the code, it worked before but now I am getting this recurring error.

case 'field_home' :
$tids =  field_get_items('node', $node, $key, $node->language);
$terms = taxonomy_term_load_multiple(array(), array('tid' => $tids));
// Gets Field Array Based on Term IDs
$name = array();
foreach($terms as $term){
$name[] = $term->name;}
$return[$key_clean] = $name;

Answer 1

Please pass $tids array direct to the function. E.g:

$terms = taxonomy_term_load_multiple($tids);

NOTE: Also before passing $tids to the function, please check it is include only tids. E.g:

$tids should be like $tids = [10,11,12,13,...];
