I've updated to Terraform 1.6.1 and terraform show now produces a list of checks for one of my modules. With 1.5.7 this output was completely omitted.

This doesn't match the expectation of the State struct that Checks is a single pointer.

Running show with the current library results in:
json: cannot unmarshal array into Go struct field rawState.checks of type tfjson.CheckResultStatic
