Async Await with moongose node js

I got a issue with es6 async/await while working on below code. The problem is if there is any error occurred during saving it is not throwing any error (like i have validation on password and using try/catch), So do i need to use promise then/catch or is there any way with this?

 var newUser = new User({
                firstname : f_name,
                lastname  : l_name,
                password : "dsadasdas",
                social:{social_id : social_id,
                             via : via},
                email : mail,
                ref_id : ref_id,
                verification_code : verification_code,
                role :"USER",
                loc: {type: "Point", coordinates: [0, 0]},
                provider: 'local',
            });


            const data = await  newUser.save()
