+Because this module uses 2 providers, `aws` and `awscc`, if your `AWS_DEFAULT_REGION` environment varaible is different than what is hard-coded in your HCL, the AWSCC provider will use the default region. This will result in no ability to find the resources with a hardcoded region. You can fix this by hardcoding a region for both environments or updating your environment variable:
+
+```terraform
+provider "aws" {
+  region = <>
+}
+provider "awscc" {
+  region = <>
+}
+```
+
+or
+
+`export AWS_DEFAULT_REGION=<>`
