model.cloneDeep is not a function

Hi, Walter, I tried to use the officail adapter for ReactJS.

At the moment I got this error:

This is my code:

I’ve tried to add a ‘cloneDeep’ function to model, but it didn’t work.
Any idea how to fix this issue?

Thank you in advance.

That method is new in version 2.1. Are you sure you are using a 2.1.* version library?

Oh. I’ve just figured out. Thank you.
