OCP 4.8 Java lab - trigger not working

[mandibuswell]

I tried the current 4.6 lab with the amended pipeline and trigger yamls for 4.7 on a 4.8 install and everything worked except the trigger step.
I used this GIST to accelerate through

[mbuswell-redhat.com@bastion agnosticd]$ oc create -f https://raw.githubusercontent.com/openshift-roadshow/nationalparks/master/pipeline/nationalparks-triggers.yaml
triggertemplate.triggers.tekton.dev/nationalparks created
triggerbinding.triggers.tekton.dev/nationalparks created
route.route.openshift.io/el-nationalparks created
Error from server (BadRequest): error when creating "https://raw.githubusercontent.com/openshift-roadshow/nationalparks/master/pipeline/nationalparks-triggers.yaml": admission webhook "webhook.triggers.tekton.dev" denied the request: mutation failed: cannot decode incoming new object: json: unknown field "name"

In addition of course, the imagery will need updating.

I have confirmed that by setting the name to ref in template this works
