Does anyone know how to merge tags? I am working on code in Azure that is used in multiple environments.

my main.tf file contains:

tags ={
  application     =  "Myapp"
  BU              =  "IT"
  DeploymentMode  = "terraform"
  Environment     =  "Production"
  }

4 environments in all(Production, Staging, Development, Test)

terraform login
terraform workspace list

Production
Staging
Development
Test

I want to appl they changes to the Test workspace.

terraform workspace select Test

terraform validate
terraform init

all work with no issues.

I then run terraform plan
Part of the code returned includes:

 ~tags    = {
    ~ Environment = "Test" -> "Production"}

I suspect this means changing the environment. Which isn’t what i want.

My research tells me i need to merge the tags. Not sure how to do this.
