Routing bug (and not bug)(Confusing)

Hi guys, i am here to talk about a bug, i have my developing app working fine, without any errors on debug and build, but in any web browser, i am getting this errors, like the image below:

But the app is working without any problems, like the images below:

So what i am doing wrong here? The routes are fine in mobile build, so why only in web browser gives this error?
