app.post('/productsByKeys',(req,res)=> {
  console.log("found:ids",req.body)
  const productKeys = req.body;
productCollection.find({_id: {$in :ObjectID(productKeys)}})
  .toArray((err,items)=> {
      res.send(items);
      console.log(" found by ids: ",documents)
      console.log("RESPONSE :",err)
  })

Instead of converting you array into ObjectId(), convert individual items inside the array into ObjectIds.

const productKeys = req.body;
let convertedKeys = productKeys.map((x) => ObjectID(x));

productCollection.find({_id: {$in :convertedKeys}})
