ERROR Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: 'menu'

So what does this error mean?

In my case, I had a routing error in my app-routing.module.ts file in which I had the path with a variable parameter, this is what I had:

path: 'menu/:xyz',

I changed it to this:

path: 'menu',

and it worked.
