Router.push() in boot file gives error on HMR

[CrawfordW]

I have a firebaseBoot file which detects auth changes and if the user is logged in, opens the app by pushing the main layout page to the router. This works fine normally, but on hot reloads after changing any file, it registers an error on the Router.push() line. Still works despite the error.

Note: I recently switched from webpack to vite. I don't recall seeing this error with webpack.

More info:
After hot reload, the router remains undefined. I get the error on any route changes. A normal refresh fixes it.
