OpenIDM can't create managed user: "openidm" (object) is not defined (e.g. openidm.create(...) )

[jimmydevenportdxc]

Describe the bug
Upon trying to create a new managed user with the "out of the box" OpenIDM 5.5.0, the openidm0.log.0 shows this error:
Jul 23, 2020 11:16:13 PM org.forgerock.openidm.servlet.internal.ServletConnectionFactory$3 handleException
WARNING: Resource exception: 500 Internal Server Error: "onCreate script encountered exception"

To Reproduce
Steps to reproduce the behavior:

1. Unzip the latest openidm-5.5.0.zip
2. /path/to/openidm/startup.sh
3. open browser to localhost:8080/admin and authenticate as openidm-admin/openidm-admin
4. Select Manage->User from menu
5. Click the "+ New User" button
6. Fill out required fields on Details tab and Password tab, and click Save button
7. Browser gets 500 error, go to /path/to/openidm/logs and look at openidm0.log.0 file
8. Error shows in file, user not created

Expected behavior
Should be able to create a user with no errors. Should also be able to use "openidm" object in custom endpoints, e.g. openidm.create, openidm.read, openidm.query, openidm.update, openidm.delete, openidm.action, etc.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Red Hat Enterprise Linux 8
• Browser any

Additional context
I tried with default orientdb as the repo and with MySQL as the repo, same issue. /path/to/openidm/bundle folder shows openidm*.jar and "scr list" on console shows they are active, but it appears that Rhino doesn't load them?
