How to read from terraform backend resource variables / values in another resource

Terraform
#1

Hello,

In my scenario I cannot determine the values being sent to the terraform executable and need to read from the backend configuration that is piped into terraform - in this particular case i need to read from the terraform.backend.address (it is of http backend type)

What is the correct format to access this in another resource?

For example:

output “terraform_test” {
value = backend.config.address
}

on outputs.tf line 2, in output "terraform_test": │ 2: value = backend.config.address │ │ A managed resource "backend" "config" has not been declared in the root │ module. ╵

Thank you

I cannot determine the values being sent to the terraform executable nor the environment TF_VARs
