How to save and load a OPLS model with nodejs?

[JiayiHong]

Hello,

I have trouble saving and loading the OPLS model. I tried to load a OPLS model with PLS.OPLS.load(obj) but it has an error like the below:
OPLS.js:355 Uncaught (in promise) TypeError: model.wOrth.transpose is not a function in OPLS.js:355.
My codes are like below:
`const model = pls.toJSON();
exportJsonFile("pls", model);

const obj = await fetchJson('pls.json');
const pls = PLS.OPLS.load(obj);
const result = pls.predict(testSetx, { trueLabels:testSety});`

Thank you so much in advance!

It's probably a bug. You code seems correct.
