Uncaught Error: Unable to find global parent component window

[Oleksandr200]

We faced out the issue when we have the zoid iframe and the zoid child component on the same domain. The rendering library is react on both sides.

The parent zoid component lays on https://domain/parent-path/index.hml
The child zoid component url is https://domain/child-path/index.html

As I see Zoid set type of parent window as GLOBAL

zoid/src/parent/parent.js

Line 646 in 2ef6fdb

if (initialChildDomain === getDomain(window)) {

and then it cannot find this global window.

What does it mean GLOBAL type of window?
What conditions should be observed that zoid could work in one domain?

I was getting this same error after upgrading from 9.0.63 to 10.3.3. What ended up fixing it was changing the domain property to allowedParentDomains in the create method (along with putting my domain string in brackets as allowedParentDomains in an array).
