I am using a query getUsers to fetch the user by passing the token to header

let user
getUsers: async (_,__,context) => {
        
            if(context.req && context.req.headers.authorization){
                const token = context.req.headers.authorization.split("Bearer ")[1]
                jwt.verify(token, JWT_SECRET, (err, decodedToken) =>{
                    if(err){
                    throw new AuthenticationError("Unauthenticated")
                     }
                     
                     user = decodedToken

                    console.log(user)
                 })
            }

But this is throwing the error "Unauthentication", When I tried to console.log(decodedToken). It was showing undefined. How can I overcome this?
