terraform {*} panics when on Terraform Plan files

[scottford-io]

Describe the bug
Running the query terraform {*} when connected to a Terraform Plan resource triggers a panic in cnquery/cnspec:

cnspec run terraform plan tfplan.json -c "terraform {*}"
→ user requested to ignore .terraform
→ loaded configuration from policy-development.yaml using source $MONDOO_CONFIG_PATH
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x0 pc=0x10584bd00]
