EQA9887E IBM® z/OS® Debugger - workstation failed the license check. The enclave will be terminated.

Explanation
z/OS Debugger called IFAEDREG to check for an enabled
product registration for Application Delivery Foundation for z/OS, IBM Developer for z/OS Enterprise Edition, or IBM Debug for z/OS. No
enabled product registration was found. The TEST parm specified that remote debug mode was to be
used, so the debugger asked the workstation whether it was licensed (typically as IBM Developer for z/OS, IBM Wazi Developer for Red Hat CodeReady Workspaces, or
IBM Z and Cloud Modernization Stack).
Either the workstation code was not licensed or was too old to respond with license information
(older than Rational® Developer for System z® 9.5.1).

Programmer response
License the workstation or use a newer workstation code
that can respond with license information.
