Response assertion error on pm.sendRequest

🙋 Help
1 
pm.test("Driver:Password Rest: Reset driver password with proper data", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.message).eq("Password rest successfully done!");
});




//Now we need to try if the changed password work
pm.test("Driver:Password Rest: re-login and check if the password reset been successful",  function () {
    var jsonData = pm.response.json();

        pm.sendRequest({
            method: 'POST',
            url: pm.environment.get('url') + '/driver/login?',
            header: {
                'Authorization': 'Basic ' + btoa(pm.variables.get('driver_email') + ":" + pm.variables.get('newPassword')),
            }
        },function(err,res){
             pm.expect(parseInt(res.code)).eq(400);
        });
        
});

I have the above code, but on the last test case, the response says 200. This fails with “AssertionError: expected 200 to equal 400”. cause to fail everything even if the report is not get generated. But if the expected values match, then it shows a pass test case in the report too. how can I fix this

after so, many attempts i just figured this just after post the question in here.
We just need to do last test case in other way around

pm.sendRequest({
            method: 'POST',
            url: pm.environment.get('url') + '/driver/login?',
            header: {
                'Authorization': 'Basic ' + btoa(pm.variables.get('driver_email') + ":" + pm.variables.get('newPassword')),
            }
        },function(err,res){
            pm.test("Driver:Password Rest: re-login and check if the password reset been successful",  function () {
                //var jsonData = pm.response.json();
                pm.expect(parseInt(res.code)).eq(200);
            });
        });
