So my bonus question is solved and I am able to mount my app under whatever/pat/needed

However the routing is borked.

Using the home button / links works but for route /user mojolicous thr
+ows an error.

"None of these routes could generate a response for your GET request f
+or //user, maybe you need to add a new one?"

I have to figure out where the extra slash is coming from and where to get rid of it. Simply adding another / in the get doesn't work
