Having trouble routing to next page after button click

It doesn’t work either, there was no error showing in the console. Below is how I added,

   const onSubmit = (data, e) => {
        const {fullname,age,gender,location}= data;
        const userData = {fullname,age,gender,location,patPhoneNumber};
        firestore.collection('pat_profile').doc(auth.currentUser.uid).set({fullname,age,gender,location,patPhoneNumber});
        history.push('/WelcomePage');
         
    };
