@petar the code here wasn't regenerated and it looks like you need to run the routing.go file to do so. If you could throw this in go generate that should both make it easy for people to regenerate the code and should allow CI catch when the code has changed but not been regenerated.

Adding a line like //go:generate go run ./routing.go somewhere should do the job.
