Expected Behavior

The second run of the command should fail as the name is already present in the current organization

Actual Behavior

The command fails per logs, but returns 0 as an exit code

Steps to Reproduce

1. terraform stacks create -organization-name <your_org> -project-name "Default Project" -stack-name "manuchn-stacks-2025"
2. terraform stacks create -organization-name <your_org> -project-name "Default Project" -stack-name "manuchn-stacks-2025"
