Why are cookies not set for the domain?

Question

JavaScript

I use the library https://github.com/js-cookie/js-cookie
Example from the docs

Cookies.set('name', 'value', { domain: 'subdomain.site.com' })

For some reason it doesn't install.
If without a domain, then everything works.
Same thing with secure. Without it, it is set, but secure is not.
How to fix?
