Components crashing after upgrading to React 16.5

Components crashing with the error https://reactjs.org/docs/error-decoder.html/?invariant=185

The crash is happening when trying to set new data from API.

And the stack trace is

Versions:
react-list@0.8.10
react: 16.5.1
react-dom: 16.5.1

I don't have an example at the moment but I will try to provide one.

We are running into the same issue in our app, though unclear as of yet what’s the cause or specific steps to reproduce.

I'm seeing this with React 16.3.0 though haven't isolated the issue yet.

I encountered something similar today, but not quite the same. What I did was 2 things.

1. Make sure that not my entire component tree crashes by nesting ReactList with ErrorBoundary like so: <ErrorBoundary><ReactList /></ErrorBoundary> . That helped keeping the error bounded and not crash the entire app.
2. When I would scroll back and forth each and each component is doing an http request, what could happen was that the component that made the request was already unmounted and when the promise resolved calling this.setState would throw: "Warning: Can only update a mounted or mounting component..." To fix that, I made sure that I canceled the promise (promise.cancel()) in componentWillUnmount in the components in the list.

I'm not at all sure if this is causing the components crashing with you, but it may give you some pointers figuring it out. Good luck.

@ christiaanwesterbeek Thank you. I think Te second point you have mentioned might be able to help me.
