How to use variables while executing CLI commands in offline mode in EAP 7 ?

Issue

• How to use variables while executing CLI commands in offline mode in EAP 7 ? When running cli-scripts in offline-mode on Jboss EAP7.4, when we configure the Elytron with variables it fails with error:

{
    "outcome" => "failed",
    "failure-description" => "WFLYCTL0211: Cannot resolve expression '${test.providerURL}'",
    "rolled-back" => true
}

we are not able to use empty variables.

Jboss-CLI script for Elytron subsystem configuration:

embed-server --server-config=${CONFIG}

/subsystem=elytron/dir-context=TestDirContext:add( \
  url="${test.providerURL}", \
  principal="${test.bindDN}", \
  credential-reference={clear-text="${test.bindCredential.password}"}, \
  enable-connection-pooling=true)
