Warning: array_map(): Argument #2 should be an array in C:\xampp\htdocs\watchmov

Hello, when i want to print the taxonomy terms i get this error:

Warning: array_map(): Argument #2 should be an array in C:\xampp\htdocs\watchmovies\wp-includes\category-template.php on line 1158

I tried to change like this. The error doen’t appear again but neither do taxonomies terms.

I change:
$terms = array_map( 'get_term', $terms );
with

if ( ! is_wp_error( $terms ) ) {
		$terms = array_map( 'get_term', $terms );
	}

Any ideea?
