Terraform gives a misleading error message if an incorrect submodule name is specified

[cblkwell]

Terraform Version

Terraform v1.9.5
on darwin_arm64

Terraform Configuration Files

module "karpenter_fg_profile" {
  source  = "terraform-aws-modules/eks/aws//modules/fargate_profile"
  version = "~> v20.24"

...

Debug Output

(This isn't really relevant -- the error is correct, just misleading)

Expected Behavior

In the source given in the Terraform code, the actual source is fargate-profile, not fargate_profile. Terraform should say that that submodule does not exist within the source module.

Actual Behavior

In actuality, Terraform gives this error:

╷
│ Error: Unreadable module directory
│
│ The directory .terraform/modules/karpenter_fg_profile/modules/fargate_profile could not be read. This is a bug in
│ Terraform and should be reported.
╵

While this is true, it makes it sound like the directory exists and cannot be read, but what is actually the case is that the directory does not even exist, fargate-profile does.

Steps to Reproduce

1.terraform init
