TypeScript with user info retrieval

Hi all, am a new react / typescript developer.

I am currently trying to grab user info in Typescript/React, and am getting errors because default state is null. i added a if statement to check if null but still throwing errors.

original tutorial (using functional component)- Get info about the user | Okta Developer

I added an if statement under the use effect to check if userInfo is null.

if(userInfo !== null){

    userType = userInfo.type //Object is possibly 'null'.ts(2531)


    userType = "not logged in or error retrieving user info"


Hi Sir ,
const [userInfo, setUserInfo] = useState(null);
probably you can try like below
if (userInfo && userInfo.type)
// your code
