Relevant error:

github.com/hashicorp/terraform-provider-google/google/resource_container_node_pool.go:805 +0xb56
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x2eb9a56]

terraform-provider-google/google/resource_container_node_pool.go:805

The API response prior to the segfault contained a node pool that didn't have a "management" key. I think that's probably making Management be nil on the NodePool object, which then you can't get the child of. Probably this just needs a nil check around setting nodePool["management"].

@jgeorge300 are you able to provide the actual Terraform configuration that produced this result? our tests seem like they should cover this case.

@melinath I added the missing the provider stanza. There's really not much more to this. I started with an empty terraform project and was looking to import existing infrastructure. I encountered this issue at the beginning of the process. I did have lines for adding a GCE resource to verify my permissions and configuration.
