使用另一个循环中的变量而不会出现布尔错误

Question

所以我有这个用于输出模式的代码，它可以正常工作，但它给了我一个布尔错误。 “尝试访问 bool 类型值的数组偏移量”

我从页面 $map_location 上的另一个循环获取地址变量，并将子变量添加到 $contact_numbers 中。因为它们共享相同的内容。

有没有相对简单的方法来解决这个问题？

        // Return if not hospital post.
        if ( get_post_type() !== 'location' ) {
            return;
        }

        global $luna;
        $id_post         = get_the_id();

        $contact_numbers = get_field( 'contact_numbers', $id_post );

        if ( $contact_numbers && is_array( $contact_numbers ) ) {
        $address_schema['department'] = [];
        foreach ( $contact_numbers as $contact ) {
            $address_schema['department'][] = [
                '@type'     => $location_type ? $location_type->name : __( 'Hospital', 'luna' ),
                'name'      => $contact['label'],
                'telephone' => $contact['number'],
                ];
                if ( $map_location ) {
                $address_schema['address'] = [
