Consul K8s External Consul Server

Trying to setup consul clients in K8s via the helm chart with an external Consul cluster. The init pod will not start with this error:
MountVolume.SetUp failed for volume "consul-ca-cert"

It’s not clear from the values if there is a value that needs set? Is it global.tls.cacert? I’m assuming the cluster needs the ca cert from the external Consul server? The external consul cluster uses Vault PKI for certs FYI
