It looks like this code that try to GET request the value that send become blank-CodePudding

  const po_orders = ref([]);
      onMounted(async () => {
        const res = await axios.get("http://127.0.0.1:4914/server/po_order",{
              customername : 'ALEX',
          });
        po_orders.value = res.data;
        console.log(res);
      });

The below is ht code in the back end side

app.get('/server/po_order',(request,response)=>{
    database.collection("po_order").find({customername : request.body['customername']}).toArray((error,result)=>{
        if(error){
            console.log(error);
        }
        response.send(result);
    })
  })

The output result show of the document that not have "customername" if I change this line in backend

database.collection("po_order").find({customername : request.body['customername']})

by specific value like

database.collection("po_order").find({customername : 'ALEX'})

the result is I expected

First step

Change your frontend code like this:

const res = await axios.get("http://127.0.0.1:4914/server/po_order", {
  params: {
    customername : 'ALEX',
  }
})

When you are doing GET request, you should not pass the request body, but the params.

Second step

Change your backend code like this:

database.collection("po_order").find({customername : request.query['customername']})
