```
const vailedToken = asyncHandler(async(req, res, next)=>{
const token = req.cookies.accessToken;

console.log(token);
---stuff----
} );

});

module.exports = vailedToken;
```

and when i am testing as get route in app.js. the its showing the req.cookies with accessToken

```
app.get("/test", (req, res) => {
console.log("Cookies:", req.cookies);
res.json(req.cookies);
});
```
