Issues with React, Refract, and RxJS

Hello,

I’m trying to update to a meteor app with material from version 3.9.3 to 4.0.0. When I do the update, an error happens with the observable. I submitted an issue and they told me that the issue isn’t with material. It doesn’t make sense how the issue isn’t with material as the issue isn’t there until the update.

And I’m using React and Refract in the app and the error does appear to be coming from RxJS and subscribing to the server. I’m using ddp and the ddp-link and I don’t know if that’s affecting the observable. I don’t know if the issue is coming from the useRefract, but the object being used is an observable.
