Tutorial dies on first Build

[john2exonets]

Cloned this and tried the first step....dies with errors:

root@controller:~/Tekton/tekton-tutorial# tkn task start build
? Value for param `contextDir` of type `string`? (Default is `.`) .
? Value for param `destinationImage` of type `string`? (Default is `$(outputs.resources.builtImage.url)`) $(outputs.resources.builtImage.url)
? Value for param `dockerFile` of type `string`? (Default is `Dockerfile`) Dockerfile
? Value for param `tlsVerify` of type `string`? (Default is `false`) false
Error: the API version in the data (tekton.dev/v1beta1) does not match the expected API version (tekton.dev/v1)

So....dolefully change the 'v1beta1' to 'v1', and still dies:

root@controller:~/Tekton/tekton-tutorial# nano tekton/2.tasks/build-task.yaml 
root@controller:~/Tekton/tekton-tutorial# kc apply -f tekton/2.tasks/build-task.yaml 
Error from server (BadRequest): error when creating "tekton/2.tasks/build-task.yaml": admission webhook "webhook.pipeline.tekton.dev" denied the request: mutation failed: cannot decode incoming new object: json: unknown field "resources"

Can't even get it to apply the change :(
