Receiving a "element() may not be used with an empty list in" error #8

I'm receiving this error message after trying to spawn the multi region cluster, the only difference between the actual example is that I have two nodepools attached to the "google_container_cluster" resource.

${element(module.k8s_primary_cluster.instance_groups, 0)}

Once I run again apply it works normally as it is able to get the module.k8s_primary_cluster.instance_groups elements. As for the moment 4 instances are being provisiones.

This might be an upstream terraform issue as it sounds like it may not be waiting for the associated node pools to be created before updating it's instance_group_urls state.

Can you try again with the latest provider and terraform version? If it's still an issue, my suggestion would be to submit and issue to the terraform-provider-google repo.
