You have to pass the object with properties defined in schema Model to the creation function (in your case the object with names property). You are passing the imgNames array. Change you code like this:

await ImgArray.create({ names: imgNames });

your model need to have a field that accepts array like this:

const ImgArraySchema = mongoose.Schema({
names: [{
type: String,
required: true
}]
})

then to save an array, do it like this:

const imageArray = new ImgArray({names: imgNames})
const imgarray = await imageArray.save()
.catch((err) => (res.status(500).send({err: err.message})))
if (imgarray) {
return res.status(200).send({success: true, imgarray})
}
return res.status(400).send({success: false, error: ""})
