Another route has already been assigned name: when using Multiple domains on Panels (multiple)

Error when using multiple domains in a panel:

Unable to prepare route [two-factor-authentication] for serialization. Another route has already been assigned name [filament.central-admin.auth.two-factor].

The fix is that the name of the route should contain the domain suffixed in the route name in web.php. like so: ->name(!empty($domain) ? "{$panelId}.{$domain}." : "{$panelId}.")

Route::domain($domain)
                    ->middleware($panel->getMiddleware())
                    ->name(!empty($domain) ? "{$panelId}.{$domain}." : "{$panelId}.")
                    ->prefix($panel->getPath())
