Node.js 节点js delete代码生成意外错误

我试图删除节点项目中的一篇文章，但它抛出了一个错误。即使在那个时候，Delete仍然可以正常工作，但我无法找出产生此错误的原因和位置

我已尝试在控制台中打印步骤。请帮我找出是什么错误

路由器

.delete(cors.corsWithOptions, authenticate.verifyUser, (req, res, next)=>{
    Posts.findById(req.params.postId)
    .then(async (post) => {
        console.log('Post with id: '+req.params.postId+' found!');
        if(String(req.user._id) === String(post.posted_by)){
            if(post.image){
                fs.unlink('public/uploads/images/'+post.image  , async (err) => {
                    if (err) next(err);
                    console.log('file was deleted');
                });
            }
            post.remove()
            .then((resp) => {
                console.log('Post with id: '+req.params.postId+' removed!');
                // res.statusCode = 200;
                // res.setHeader('Content-Type','text/html');
                res.redirect('/');
            })
            .catch((err) => next(err));
        }
        else{
            var err = new Error('You are not allowed to delete someone else\'s post!');
            err.status = 403;
            next(err);
        }
    }, (err) => next(err))
    .then((err) => next(err));
    
    // Posts.findByIdAndRemove(req.params.postId)
    // .then((resp) => {
    //     res.statusCode = 200;
    //     console.log('Post deleted', resp);
    //     res.setHeader('Content-Type','text/html');
    //     // alert('The post has been deleted!');
    //     res.redirect('/');
    // }, (err) => next(err))
    // .catch((err) => next(err));
});

错误：

我会这样做，它会清除所有的回调混乱

另外请注意，您可能会遇到文件路径问题，您可能需要将

添加到

/public/…

//不需要在路由中
const removeFile=（文件路径）=>{
返回新承诺（（解决、拒绝）=>{
试一试{
fs.取消链接（文件路径，（错误）=>{
如果（错误）抛出错误；
log（'文件已删除'）；
解决（）
});
}捕捉（错误）{
拒绝（错误）
}
})
}
app.delete（cors.corsWithOptions、authenticate.verifyUser、async（req、res、next）=>{
试一试{
const post=wait Posts.findById（req.params.postId）
log（`Post with id:${req.params.postId}找到！`）；
if（字符串（请求用户id）！==字符串（发布人））{
var err=new Error（'不允许删除其他人的帖子！'）；
err.status=403；
犯错误；
}
if（post.image）等待删除文件（`public/uploads/images/${post.image}`）
等待发布。删除（）
log（`Post with id:${req.params.postId}已删除！`）；
res.redirect（'/'）；
}捕捉（错误）{
下一个（错误）
}
});
