 Terraform module which creates AWS Global Accelerator resources.
 
-#### ℹ️ `Error: Invalid for_each argument ...`
-
-Users may encounter the following error when using this module:
-
-```
-Error: Invalid for_each argument - The "for_each" value depends on resource attributes that
-cannot be determined until apply, so Terraform cannot predict how many instances will be
-created. To work around this, use the -target argument to first apply ...
-```
-
-This error is due to an upstream issue with [Terraform core](https://github.com/hashicorp/terraform/issues/4149).
-
-The Terraform resource passed into the modules map definition (specifically, endpoint targets) _must_ be known before you can plan or apply the module. To help mitigate this issue, you can do one of the following:
-
-1. Create the dependent resources before the accelerator => `terraform apply -target <your load balancer endpoints or ec2 instances>` and then `terraform apply` to create the accelerator and associated resources
-2. Create the dependent resources elsewhere prior to referencing in the module defintion
-
 ## Usage
