This object does not have an attribute named "xxxx"

Terraform
1

I work with 2 projects i.e. 2 state files, where I need to access some info from the first one in the second one. So in the first one I declare output.tf

output "project-member_id" {
  description = "Project Member ID"
  value       = rancher2_role_template.project-member.id
}

output "read-only_id" {
  description = "Read Only ID"
  value       = rancher2_role_template.read-only.id
}

output "cluster-read-only_id" {
  description = "Cluster Read Only ID"
  value       = rancher2_role_template.cluster-read-only.id
}

In the second project, I consume it as follows:

locals {
   prtbs = flatten([
      for projectname,project in local.projects : [
         for role, details in project.members: {
            ....
            role_template_id   = data.terraform_remote_state.prd-local-state.outputs["${details.role}"]
            ....
         }
      ]
   ])
}

If I to a terraform plan I get this error

│ Error: Unsupported attribute
│ 
│   on /atlantis-data/repos/Kubernetes/rancher-tf-prd/25/default/prd-project1/projects_namespaces.tf line 7, in locals:
│    7:             role_template_id   = data.terraform_remote_state.prd-local-state.outputs["${details.role}"]

│     │ data.terraform_remote_state.prd-local-state.outputs is object with 1 attribute "read-only_id"
│ 
│ This object does not have an attribute named "cluster-read-only_id".

When I do declare output.tf in the project 2, where I am referencing the output values from project 1, that works fine

output "project-member_id" {
  description = "Project Member ID"
  value       = data.terraform_remote_state.prd-local-state.outputs["project-member_id"]
}

output "read-only_id" {
  description = "Read Only ID"
  value       = data.terraform_remote_state.prd-local-state.outputs["read-only_id"]
}

output "cluster-read-only_id" {
  description = "Cluster Read Only ID"
  value       = data.terraform_remote_state.prd-local-state.outputs["cluster-read-only_id"]
}

terraform plan of project 2 shows

Changes to Outputs:
+ cluster-read-only_id = "rt-xxxxx"
+ project-member_id    = "rt-xxxxx"
+ read-only_id         = "rt-xxxxx"

I have successfully used the same approach in other projects, but somehow here it does not work. If I extend the output.tf from project 1 as follows

output "project-member_id" {
  description = "Project Member ID"
  value       = rancher2_role_template.project-member.id
}

output "read-only_id" {
  description = "Read Only ID"
  value       = rancher2_role_template.read-only.id
}

output "cluster-read-only_id" {
  description = "Cluster Read Only ID"
  value       = rancher2_role_template.cluster-read-only.id
}

output "roleids" {
  description = "IDs for roles"
  value = {
    read-only_id=rancher2_role_template.read-only.id
    project-member_id=rancher2_role_template.project-member.id
    cluster-read-only_id=rancher2_role_template.cluster-read-only.id
  }
}

And use it as follows in the second project

locals {
prtbs = flatten([
for projectname,project in local.projects : [
for role, details in project.members: {
…
role_template_id = data.terraform_remote_state.prd-local-state.outputs.roleids[“${details.role}”]
…
}
]
])
}


I still get the error

What am I doing wrong?

Interesting, the output shows what I expect, but when checking the data, I see different things

data.terraform_remote_state.prd-local-state.outputs
{
  "read-only_id" = "rt-xxx"
}

Whereas another project using the exact same data source works fine

> data.terraform_remote_state.prd-local-state.outputs
{
  "roleids" = {
    "cluster-read-only_id" = "rt-xxxxx"
    "project-member_id" = "rt-xxxxx"
    "read-only_id" = "rt-xxxxx"
  }
  "cluster-read-only_id" = "rt-xxxxx"
  "project-member_id" = "rt-xxxxx"
  "read-only_id" = "rt-xxxxx"
}
```

Looks like an issue with the provider, I updated the backend config from a fixed version to

  required_providers {
      rancher2 = {
          source = "rancher/rancher2"
          version = "~>1.22.2"
      }
      kubernetes = {
        source = "hashicorp/kubernetes"
        version = "~>2.11.0"
      }
      kubectl = {
        source  = "gavinbunney/kubectl"
        version = "~>1.14.0"
      }
  }
