After doing some digging, seems that the create-next-app defaults to using the v2 route convention but the tutorial has not been updated. You can adjust by turning off v2_routeConvention in remix.config.js

Yeah this looks like the tutorial is just a bit stale and need to be updated to reflect the v2 routing structure. We'd happily accept a PR for this if someone wants to give it a shot!
