Missing documented workflow properties rest api.

I tried to make a request to the following rest resource:

And got a 404. When I looked through the JIRA source code I could not even see that resource implemented in com.atlassian.jira.rest.v2.admin.WorkflowsResource

However, it is documented in the pubilic JIRA documentation as though it exists: https://docs.atlassian.com/jira/REST/latest/#api/2/workflow-getProperties

What is wrong? The documentation or the source code. I'm writing the documenation around entity properties for Atlassian Connect right now so this will affect those docs.

Note: I am developing with AMPS and my JIRA version is v7.1.0-OD-02-025#71001-sha1:64a64e8. I have also tried browsing with the Rest API Browser and don't see the documented rest resources from there either. Cheers.
