replace_triggered_by doesn't report error if given attribute references don't exist

[ellisonch]

Terraform Version

Terraform v1.11.2
on linux_amd64

Terraform Configuration Files

resource "null_resource" "r1" {
}

resource "null_resource" "r2" {
    lifecycle {
        replace_triggered_by = [null_resource.r1.foo.bar.baz[0].bif] # does not error, but should
        # replace_triggered_by = [null_resource.r3] # correctly reports error
    }
}

Debug Output

none

Expected Behavior

I expect the configuration above to yield an error. null_resource.r1.foo.bar.baz[0].bif is not a real attribute reference.

Actual Behavior

$ terraform apply
null_resource.r1: Refreshing state... [id=1800298252482723122]
null_resource.r2: Refreshing state... [id=3647057674329973682]

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

Steps to Reproduce

1. terraform init
2. terraform apply

Additional Context

Since replace_triggered_by is expecting a list of resources or attributes, I'd expect that it would check that those references at least were valid references. It's extremely easy to make a mistake here (e.g., forgetting [0], or a typo, etc) and for a resource not to get replaced because of that typo.
