Remote scripting and get_equivalent function

Hello, I am using remote scripting on Plaxis 3D (usign Spyder), and I am having an issue when trying to use the function get_equivalent (to obtain an equivalent entity on Plaxis Output). I am following the example script for the addcurvepoint command found in the Scripting Reference. Towever, the function does not seem to be included in the "plxscripting.easy" module, or at least Python can't find it. Is it possible that my "plxscripting.easy" module is outdated? Am I missing some step? Alternatively, I would appreciate an indication on how to find entities in Plaxis Output to be able to add curve points without using the get_equivalent function. 

Here is the section of the code, in which I try to define existing points as "curvepoints" in a specific entity (a plate)

Thank you.
