使用查询监视器插件-我遇到了这个错误Undefined property: WP_Post_Type::$ID 对于此功能：

public function add_form_modal() {
    $button_group = get_post_meta( get_queried_object()->ID, \'button_group\', true );

    if ( empty( $button_group ) || ! is_array( $button_group ) ) {
        return \'\';
    }

    if ( \'form\' !== $button_group[\'button_type\'] ) {
        return \'\';
    }

    $form_id = $button_group[\'button_link\'];
    ?>
    <div class="lsx-modal modal fade" id="cf-modal-<?php echo esc_attr( $form_id ); ?>" role="dialog">
        <div class="modal-dialog">
            <div class="modal-content">
                <button type="button" class="close" data-dismiss="modal">&times;</button>

                <div class="modal-header">
                    <h4 class="modal-title"><?php echo esc_html( $button_group[\'button_text\'] ); ?></h4>
                </div>

                <div class="modal-body">
                    <?php echo do_shortcode( \'[caldera_form id="\' . $form_id . \'"]\' ); ?>
                </div>
            </div>
        </div>
    </div>
    <?php
}
