Error with "Unapplied dependency and mock outputs" #4829
Description
Describe the bug
I have an implicit stack with two root modules: k8s-cluster and observability:

When I run terragrunt run --all validate or plan from the folder containing k8s-cluster and observability I am getting this unexpected error:

All those outputs from k8s-cluster haven't been applied yet, they are properly defined though:
$ cat k8s-cluster/outputs.tf
output "api_endpoints" {
description = "A map with different kinds of endpoints to reach the K8s API"
value = module.oke.cluster_endpoints
}
output "ca_cert" {
description = "The CA certificate in use on the K8s API"
value = module.oke.cluster_ca_cert
}
output "vcn_id" {
description = "The id of the VCN of the K8s cluster"
value = module.oke.vcn_id
}
output "vcn_nat_route_table_id" {
description = "The id of the NAT routing table to allow a private subnet to egress to the Internet"
value = module.oke.nat_route_table_id
}
output "vcn_workers_nsg_id" {
description = "The id of the Network Security Group of the worker nodes"
value = module.oke.worker_nsg_id
}
output "vcn_operator_nsg_id" {
description = "The id of the Network Security Group of the operator nodes"
value = module.oke.operator_nsg_id
}
output "vcn_bastion_nsg_id" {
description = "The id of the Network Security Group of the bastion nodes"
value = module.oke.bastion_nsg_id
}
output "state_id" {
description = "A randomly generated id to identify resources from this particular \"instance\""
value = module.oke.state_id
}
$
A terragrunt plan from the k8s-cluster properly shows that those outputs would be populated.
Expected behavior
As documented?
Versions
- Terragrunt version: v0.86.0
- OpenTofu/Terraform version: OpenTofu v1.10.6
- Environment details (Ubuntu 20.04, Windows 10, etc.): linux_amd64 / NixOS unstable.
Additional context
I am happy to run terragrunt in delve with debug symbols, if you help me navigate the code base a bit. I am kalessin14 on discord fwiw.
