Error custom routing plugin

I am making a router but have the following error.
Please help me, thanks !

Route of plugin User
50%20PM

Route of plugin Category
44%20PM

Path plugin User
12%20PM

Path plugin Category => error
00%20PM

Well… the fix is pretty much literally there: you have to create a CategoriesController as the location specified in the error containing atleast the code specified in the little code box.
