setCenter returns error on go back: InvalidValueError

[Mspellman2195]

I inherited an application from a team that is using this package to display a map w/ markers on it. My issue is that when i click on something on the page and then return via the back button the map fails to reload with the below error:
InvalidValueError: setCenter: not a LatLng or LatLngLiteral with finite coordinates: not an Object

    const onLoad = useCallback(
        function onLoad(mapInstance) {
            console.log('SETTING MAP INSTANCE.');
            setMapRef(mapInstance);
            setMapChanged(false)
            setCenter({ lat: Number(searchState?.center[0]), lng: Number(searchState?.center[1]) })
        }
    )

This is the onLoad function i'm using w/ the GoogleMap component. searchState here is the variable representing an object being passed from a context provider that is holding the current location data the map should display. For some reason on page return searchState isn't being populated which is causing the error.

Will try to recreate this issue in codesandbox and update this with the link...
