Syntax error: Illegal Break Statement on using next in middleware to pass to other middleware

Question

I am trying to use a middleware to verify my user token. The problems come when I am trying to use next() to move on to the next middle were. What I think is that somehow my next() is not working as it should. Please help.

Middleware code:

async function verify(req,res,next){

    if(req.body.token==null) next("Tokken Not present")
    // verify token
    try{

        var isAuth=jwt.verify(req.body.token,process.env.secretKey);
       if(isAuth)next();
    }catch(err){
        next(err)
    }

}

error msg:

no i just want to move my req to next middleware when token is sucessfuly verified.Bascially the above function is for verify.Since i have to verify several times i have made it as sep middleware — Pankaj Shukla, Jun 14 '20 at 01:46

    async function verify(req,res,next){

    if(req.body.token==null) 
        return next("Tokken Not present")
    // verify token
    try{

        var isAuth=jwt.verify(req.body.token,process.env.secretKey);
       if(isAuth)next();
    }catch(err){
        next(err)
    }

}

    app.use((error, request, response, next) => {
    response.status(500).send('error') 
})
