Does anyone use this crap with typescript? How do you use NavigationGuardNext if it accepts nothing that is listed as param?

[jumika]

function handleRoute(...): RouteLocationRaw | undefined {...}

onBeforeRouteUpdate((to, from, next) => {
next(handleRoute(to)); // Type error here: Argument of type 'string | RouteLocationAsRelativeGeneric | RouteLocationAsPathGeneric | undefined' is not assignable to parameter of type 'NavigationGuardNextCallback'.
});

Why is this happening? I know this is more like a typescript issue, but i think this is very common scenario. How to solve this?
