### Terraform Version ```shell Terraform v1.9.8 on linux_amd64 + provider registry.terraform.io/hashicorp/kubernetes v2.21.1 + provider registry.terraform.io/hashicorp/null v3.2.3 ``` ### Terraform Configuration Files ```terraform terraform { required_providers { kubernetes = { source = "hashicorp/kubernetes" version = "~> 2.21.1" } } } provider "kubernetes" { config_path = "~/.kube/config" } terraform { backend "kubernetes" { } } resource "null_resource" "example" { provisioner "local-exec" { command = "echo 'foobar'" } } ``` ### Debug Output https://gist.github.com/tschneider-aneo/111f80d3f6566277d489b3078957277e ### Expected Behavior My backend secret suffix gets correctly created as "foo-3" ### Actual Behavior Terraform somehow considers the "-[1-9]" ending as an index for an object of length 1, resulting in an index out of range Terraform crash ### Steps to Reproduce terraform init -upgrade -reconfigure -backend-config="secret_suffix=foo-2" ### Additional Context _No response_ ### References _No response_
