Terraform apply output only

I'm trying to apply only the output variable definition. Here is the "output" I want to apply.

output "environment_information" {
   value = {
      foo = "value1"
      bar = "value2"
   }
}

Altough I added the "bar" as a new variable, I cannot see anything when I applied it by using the following Terraform command:

terraform apply -target=output.environment_information

Any idea? Is it possible to apply output without any resource/module definition? Thank you.

Running terraform apply -refresh-only should take care of any new outputs. It will read the latest data from each resource and then update all of the outputs in terms of those updates, which includes re-evaluating your output expressions to incorporate any changes.
