Command info:
Terraform binary: tofu
Terraform command: plan
Arguments and flags: []
Component: keycloak_sg
Terraform component: sg
Stack: deploy/dev/us-east-1
Working dir: components/terraform/sg

Executing command:
/opt/homebrew/bin/tofu workspace select -keycloak_sg
Usage: tofu [global options] workspace select NAME

  Select a different OpenTofu workspace.

Options:

    -or-create=false    Create the OpenTofu workspace if it doesn't exist.

    -var 'foo=bar'      Set a value for one of the input variables in the root
                        module of the configuration. Use this option more than
                        once to set more than one variable.

    -var-file=filename  Load variable values from the given file, in addition
                        to the default files terraform.tfvars and *.auto.tfvars.
                        Use this option more than once to include more than one
                        variables file.
Error parsing command-line flags: flag provided but not defined: -keycloak_sg


Executing command:
/opt/homebrew/bin/tofu workspace new -keycloak_sg
Usage: tofu [global options] workspace new [OPTIONS] NAME

  Create a new OpenTofu workspace.

Options:

    -lock=false         Don't hold a state lock during the operation. This is
                        dangerous if others might concurrently run commands
                        against the same workspace.

    -lock-timeout=0s    Duration to retry a state lock.

    -state=path         Copy an existing state file into the new workspace.


    -var 'foo=bar'      Set a value for one of the input variables in the root
                        module of the configuration. Use this option more than
                        once to set more than one variable.

    -var-file=filename  Load variable values from the given file, in addition
                        to the default files terraform.tfvars and *.auto.tfvars.
                        Use this option more than once to include more than one
                        variables file.
