Expected Behavior

Return results for strings in tags that contain a dash -

Current Behavior

## Terraform definition

ec_deployments

Steps to Reproduce

Running

data "ec_deployments" "cross_cluster_sources" {
  tags = {
    "region"               = "us-east-1"
  }
}

Context

does not return clusters that contain this in tags.

Possible Solution

Inserting the tags by replacing dashes with underscores and then doing the same when searching for deployments.

data "ec_deployments" "cross_cluster_sources" {
  tags = {
    "region"               = replace(var.region, "-", "_")
  }
}
