Element ref was specified as a string (file-input) but no owner was set...

Hi, I trying to use material-ui-upload, but see an errors related to new React version:

Error: Element ref was specified as a string (file-input) but no owner was set. You may have multiple copies of React loaded. (details: https://fb.me/react-refs-must-have-owner).

My env: React v16.2.0 Meteor v1.6.1 Node.js v9.4.0

Link to docs:
