### Terraform Version ```shell Terraform v1.10.0 on linux_amd64 ``` ### Terraform Configuration Files ```terraform variable "tfc_vault_backed_aws_dynamic_credentials" { description = "Object containing Vault-backed AWS dynamic credentials configuration" type = object({ default = object({ shared_credentials_file = string }) aliases = map(object({ shared_credentials_file = string })) }) } provider "aws" { shared_credentials_files = [var.tfc_vault_backed_aws_dynamic_credentials.aliases[""].shared_credentials_file] } provider "vault" { skip_child_token = true } ``` ### Debug Output ``` {"@level":"error","@message":"Error: Can't change variable when applying a saved plan","@module":"terraform.ui","@timestamp":"2024-11-27T11:02:58.014345Z","diagnostic":{"severity":"error","summary":"Can't change variable when applying a saved plan" ``` ### Expected Behavior Terraform applies the detected changes. Reverting the Terraform Cloud workspace to version `1.9.8` fixes this. ### Actual Behavior Terraform fails with the following error: ``` Error: Can't change variable when applying a saved plan The variable tfc_vault_backed_aws_dynamic_credentials cannot be set using the -var and -var-file options when applying a saved plan file, because a saved plan includes the variable values that were set when it was created. ``` ### Steps to Reproduce 1. Make sure workspace uses Terraform v1.10 (latest) 2. Click `New run` on Terraform cloud 3. Start new `Plan and apply (standard)` run ### Additional Context The `tfc_vault_backed_aws_dynamic_credentials` variable is passed via Terraform Cloud variable sets. ### References _No response_
