sampler methods in docs throw error "function not found"

[pnyboer]

I'm trying to learn more about scripting a Sampler. I've been going through the docs and have been getting several errors with some of the selection methods.
https://docs.hise.audio/scripting/scripting-api/sampler/index.html

I tried to create a basic selection with

const var MPOneShot = Synth.getSampler("MP One Shot");
var select = MPOneShot.selectSounds("Clap Broken_40.wav");
MPOneShot.createListFromScriptSelection();

but it throws a function not found error in the console for the createListFromScriptSelection.
I have a similar issue with the createSelection method.

Ultimately I'm trying to create an array of the names of samples in the Sample Map, I was hoping this would take me in the right direction!

Try Sampler.createListFromScriptSelection();

Within a Sampler's MIDI Script processor in onInit, I tried the simplest thing I could think of for this:

Sampler.selectSounds("_");
Sampler.createListFromScriptSelection();

throws
constant not found: Sampler.createListFromScriptSelection {U2NyaXB0IFByb2Nlc3NvcjJ8fDk1fDN8Mzg=} Script Processor2:! Line 3, column 38: Function / constant not found: Sampler.createListFromScriptSelection
