Mock server not returning subdirectories/urls

[jknight]

Starting in docker image with:
docker run -p 8080:8080/tcp -it --rm -v $PWD:/doc quay.io/bukalapak/snowboard mock -b :8080 api.apid

Endpoints available:

[...]
PUT /order
PUT /order/create   
[...]

browse to http://localhost:8080/order - returns json as expected
browse to any sub location, ie http://localhost:8080/order/create: "Not Found"

This is true for any B-level endpoint (http://localhost:8080/A/B)
