jx: GC cronjob actions failing?

Using:

NAME VERSION jx 1.2.133 jenkins x platform 0.0.1175 kubernetes cluster v1.9.7-gke.1 kubectl v1.9.6 helm client v2.9.1+g20adb27 helm server v2.9.1+g20adb27 git git version 2.15.1 (Apple Git-101)

I am seeing lots of failed pods on our cluster with names starting with jenkins-x-gc-activities and jenkins-x-gc-previews. Looks like there is an issue with permissions as the logs are reporting:

error: pipelineactivities.jenkins.io is forbidden: User "system:serviceaccount:jx:default" cannot list pipelineactivities.jenkins.io in the namespace "jx": Unknown user "system:serviceaccount:jx:default"
