Handlebars Form no run Mongodb delete function - typeError gfs.deleteOne - mongodb

Question

The form below sends images/files to Mongodb using the handlelebars (.hbs) engine and multer-gridfs-storage (Mongodb FIles), but by clicking delete it generates the following error:
TypeError: gfs.deleteOne is not a function
Also, it does not load the thumbnail of the attached photo
Ps: I think the error is in HBS form.

files.map(file => {

file.contentType === 'image/jpeg' ||

app.delete('/files/:id', (req, res) => {
gfs.deleteOne({ _id: req.params.id, root: 'uploads' }, (err, GridFSBucket) => {
if (err) {
return res.status(404).json({ err: err });
}
res.redirect('/');
});
});

Answer 1

gfs.files.deleteOne({ filename: req.params.filename}, (err) => {
if (err) return res.status(500).json({ success: false })
return res.json({ success: true });
})
using the above will delete the file
