Migrating from EAP 6.4 to EAP 7.x and unable to call /subsystem=undertow:add()

Issue

• We are migration from JBoss EAP 6.4 to 7.2 and we use cli-scripts to build up our JBoss profile configuration from scratch and are unable to add the undertow subsystem:

[standalone@embedded /] /subsystem=undertow:add
{
    "outcome" => "failed",
    "failure-description" => "WFLYCTL0369: Required capabilities are not available:
    org.wildfly.undertow.host.default-server.default-host; Possible registration points for this capability:
