acf_extract_var() throws php warning

api-template.php has the following lines (564 and 565):

$field = get_field_object( $selector, $post_id, false );
$value = acf_extract_var( $field, 'value' );

The problem is that get_field_object() can return a boolean, but acf_extract_var() doesn’t check to see if $field is actually an array, so you get:

Warning: array_key_exists() expects parameter 2 to be array, boolean given in ...\plugins\advanced-custom-fields-pro\api\api-helpers.php on line 845
