I working on an app where I have to receive data from back which contains `userdetail` object.

I want to assign a current accessToken to the userdetail object in my code:

```
useEffect(() => {
        if (session?.user && pageLoad) {
            try {
                axios
                    .get(`${process.env.CONTENT_GHAR_API_URL}/auth/userDetail`, {
                        headers: {Authorization: session.user.data.accessToken},
                    })
                    .then(response => {
                        setPageLoad(false);
                        console.log("response", response);
                        if (response?.data) {

                            response.data?.message?.userDetail?.accessToken =session?.user?.data?.accessToken;
                            localStorage.setItem("uniqueId",response.data?.message?.userDetail?._id,);
                            dispatch(userDetail(response.data.message.userDetail));
                        }
                    });
            } catch (error) {
                setPageLoad(false);
            }
        }
    }, [session]);

```

When I run the app, I ended up with the error **Syntax error: Invalid left-hand side in assignment expression.**\* for the code shown above. Why? What is the correct way to update that value then?
