I used the following docs to import my old tfstate file: Configuring Terraspace with Existing Statefiles and Systems - Terraspace

I have the following bucket:

aws s3 ls terraform-state-:ACCOUNT-div-sandbox-dev --recursive
  63500 us-east-1/stacks/sofia/terraform.tfstate
135388 us-east-1/stacks/vpc-service/terraform.tfstate # old state with resources

My backend.tf file:

terraform {
  backend "s3" {
    bucket         = "<%= expansion('terraform-state-:ACCOUNT-:ENV') %>"
    key            = "<%= expansion(':REGION/:EXTRA/:BUILD_DIR/terraform.tfstate') %>"
    region         = "<%= expansion(':REGION') %>"
    encrypt        = true
  }
}

Generated:

terraform {
  backend "s3" {
    bucket         = "terraform-state-*HIDEN-div-sandbox-dev"
    key            = "us-east-1/stacks/vpc-service/terraform.tfstate"
    region         = "us-east-1"
    encrypt        = true
  }
}

Problem:

ERROR: Unable to find the div-sandbox-dev position in the prefix

How can I solve this?
