Hello Everyone, how to pin elasticsearch version using “ec” Terraform provider? I am using the following

> data "ec\_stack" "latest" {  
> version\_regex = "8.2.1"  
> region = var.region  
> }

but it throws “Error: failed to obtain a stack version matching “8.2.1": please specify a valid version\_regex” error. How to solve this issue?

According to the official documentation, you can either specify a "valid" version (but which could become invalid when the version is no longer available) or a "regex" for the version that can match a whole minor release list.  
[ec\_stack | Data Sources | elastic/ec | Terraform Registry](https://registry.terraform.io/providers/elastic/ec/latest/docs/data-sources/ec_stack)  
In your case,

```auto
data "ec_stack" "latest" {
version_regex = "8.2.?"
region = var.region
}

```

will give your version 8.2.3 today.
