Any route in web.php gives 404

I would like to add a simple route in my Filament app like below:

Route::get('/test', function () {
    dd("Here");
});

Route::get('/test', function () {
    dd("Here");
});

When I access the

/test

/test

url, Laravel throws an 404 Not Found.

What am I doing wrong?

Solution

I am using multi tenancy, and in that case I needed to set

->tenantRoutePrefix()

->tenantRoutePrefix()

on my panel.

Having a prefix, made it so I could define routes in web.php
