我创建了一个新的自定义帖子类型，用户可以从前端添加新帖子，它可以根据需要工作。现在，我正在尝试添加一个要删除的按钮。这是按钮触发的代码：

    if( has_post_thumbnail( $post_id ) ) {
        $main_image_id = get_post_thumbnail_id( $post_id );
        wp_delete_attachment( $main_image_id , true );
    }
    if( get_post_meta( $post_id , \'token_personagem\' , true ) ) {
        $token_id = get_post_meta( $post_id , \'token_personagem\' , true );
        wp_delete_attachment( $token_id , true );
    }
    wp_delete_post( $post_id );
    wp_redirect( $url );

一切似乎都如我所愿（帖子拇指被删除，第二幅图像被删除，帖子被删除，用户被重定向），但调试时出现了一个错误。日志上写着：

如何删除自定义帖子类型的帖子而不出现该错误？我错过了什么？

        if( has_post_thumbnail( $post_id ) ) {
            $imagem_principal_id = get_post_thumbnail_id( $post_id );
            wp_delete_attachment( $imagem_principal_id , true );
        }
        if( get_post_meta( $post_id , \'token_personagem\' , true ) ) {
            $token_id = get_post_meta( $post_id , \'token_personagem\' , true );
            wp_delete_attachment( $token_id , true );
        }
        wp_redirect( $url );
        wp_delete_post( $post_id );
        exit;
