Hi @r-tock , I'm sorry but I'm having trouble reproducing it.

What I can see from you logs is that the component is trying to dispatch an event through the ref this.textarea which, in your case, is null, and this causes the error.

Which version of React are you using? I'm asking because this looks like an error due to using an older version of React like v0.13

from react-autosize-textarea.

we are on the latest react 15.4.2, these are caught by rollbar.js

from react-autosize-textarea.

Is it possible that this is caused by some race condition? Maybe while the component is being unmounted.

It's possible even if we're using it in production in several projects and it never happend to us 😕

Still, I noticed that this ugly setTimeout could be easily removed by using componentDidUpdate instead of componentWillReceiveProps to manually trigger un update!

I'm hoping that removing the async setTimeout will fix your problem.
