404 error executing more than twice

When i Set 404 error the redirect execure 10 times, I d like to redict to a 404 page instead print

` $router->set404( function () {

});`

even I cannot set an error with user input wrong world for login

`$router->set404('/api(/.*)?', function() {`

Start at the router's set404 entry point and reproduce the redirect behavior described in the issue, including the /api(/.*)? pattern and repeated execution. Determine why the 404 handler runs more than twice and verify that invalid login input reaches a 404 page without repeated redirects.
