Gatsby: Get previous path/route in 404 page

[Blackglade]

Summary

Is there anyway for me to retrieve the previous page that the user was when they navigate to route that doesn't exist and hit my 404 page. I basically want my 404 page to dynamically change depending on how the user gets there. I currently have this in my gatsby-browser.js

exports.onRouteUpdate = ({location, prevLocation}) => {
    if(location !== null && prevLocation !== null){
        location.state.prevPath = prevLocation.pathname
    }
    console.log(location)
}

but the location variable seems to reset and the prevLocation is null when I navigate from a normal page to a 404 page.
