Firestore Failed to convert value of type java.lang.String to Date

Question

My Firestore date format

In My fragment I get the date in this way

Query query = fb.collection("jobs")
                .orderBy("date", Query.Direction.ASCENDING);
 protected void onBindViewHolder(@NonNull JobsViewHolder holder, int position, @NonNull JobsLists jobsmodel) {
                holder.setDate(jobsmodel.getDate());
...
    public void setDate(Date date) {
                da =  view.findViewById(R.id.date);
                SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
                String dateString = sdf.format(date);
                da.setText(dateString);
            }

My Job class

    private Date date;
    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

When I insert the date in FireStore I put it this way

String date_val= new SimpleDateFormat("yyyy-MM-dd",Locale.getDefault()).format(new Date());  
      jobs.put("date",date_val);

Please help me! What should I change?

You don't have to transform date to a format before saving, just simply pass the date object it will be saved to the database:

  jobs.put("date",new Date());

This will make it easier for firebase to parse it when trying to retrieve the data from the database.
