Passing parameters using React fetch to access Node API-CodePudding

I have a react project with NODE API backend. I am facing issues with the very basic fetch GET request. When passing parameters through link, it cannot be accessed at the server side.

My react function:

 const loadOptions = async (cnt) => {
      const response = await fetch(`${baseurl}/pdt/prev=${prev}&cnt=${cnt}`);
      const resJSON = await response.json();
    };

NodeJS express router code:

router.get("/pdt/:prev/:cnt", async (req, res) => {
try {
       console.log(req.params.cnt);
       console.log(req.params.prev);
      
      } catch (err) {
        res.json(err.message);
      }
    });

The result is :

Edited React code based on the answers I got above. Thank you @Phil

const response = await fetch(`${baseurl}/pdt/${prev}/${cnt}`);

It's working now.

another solution from backend

 router.get("/pdt", async (req, res) => {
 try {
   console.log(req.query.prev);
   console.log(req.query.cnt);
  
  } catch (err) {
    res.json(err.message);
  }
});

and modify request

fetch(`${baseurl}/pdt?prev=${prev}&cnt=${cnt}`)
