### Terraform Version ```shell Experienced first in v1.13.3 and again when downgrading to v1.13.0 ``` ### Terraform Configuration Files ```terraform # _config.tf provider "vault" { # ... other config ... auth_login { parameters = { # ... other config ... tfe-credentials-file = filebase64("${path.cwd}/../../../.terraformrc") } } } ``` ```terraform # main.tf module "creds" { source = "../modules/creds" # ... other config ... } ``` ```terraform # modules/creds/main.tf # ... other config ... resource "vault_kv_secret_v2" "password" { # ... other config ... } ``` Vault is configured with this plugin: https://github.com/gitrgoliveira/vault-plugin-auth-tfe ### Debug Output Apologies not in debug mode but here is an amended stdout during `terraform apply` ``` │ Error: Error in function call │ │ on _config.tf line 43, in provider "vault": │ 43: tfe-credentials-file = filebase64("${path.cwd}/../../../.terraformrc") │ ├──────────────── │ │ while calling filebase64(path) │ │ path.cwd is "" │ │ Call to function "filebase64" failed: function returned an inconsistent │ result. ``` ### Expected Behavior `terraform apply` should continue past the provider setup, creating the new Vault resources as expected e.g. ``` Terraform v1.13.3 on linux_amd64 Initializing plugins and modules... module.creds[0].vault_kv_secret_v2.password: Creating... module.creds[0].vault_kv_secret_v2.password: Creation complete after 0s [id=example/secret/data/password] Apply complete! Resources: 1 added, 0 changed, 0 destroyed. ``` ### Actual Behavior ``` │ Error: Error in function call │ │ on _config.tf line 43, in provider "vault": │ 43: tfe-credentials-file = filebase64("${path.cwd}/../../../.terraformrc") │ ├──────────────── │ │ while calling filebase64(path) │ │ path.cwd is "" │ │ Call to function "filebase64" failed: function returned an inconsistent │ result. ``` ### Steps to Reproduce 1. `terraform init` 2. `terraform apply` ### Additional Context * Terraform running in `Agent` mode in TFC/HCP Terraform. * Workspace was upgraded from v1.5.7 -> 1.13.3 initially and then unexpected behavior occurred later when config was added to create `vault` provider resources * The error received from the provider only occurs at `apply` , not on `plan`. * We downgraded to v1.12.2 and no longer received the error. ### References Potentially related: https://github.com/hashicorp/terraform/pull/37001, associated to https://github.com/hashicorp/terraform/issues/36184 Vault Plugin: https://github.com/gitrgoliveira/vault-plugin-auth-tfe, of note: > TFE/TFC generates a different token during plan and the apply stages ### Generative AI / LLM assisted development?
