cannot read properties of null(reading 'resize) phaser-split.js

I get this error.
Android. Сhrome browser.
The game launches in an iframe - Probably the error appears when the iframe dimensions are changed.
Has anyone encountered something similar?
version phaser-ce 2.20.0
webpack version 4.43

My phaser game works in an iframe too and I don’t have any problem.
Maybe if you use the stable version of phaser…

What’s on the line indicated by the error message?
