React Update on Async Rendering

[duncanheffron]

React is updating their way of handling the componentWillReceiveProps, so if you get this error.

You can update this:

componentWillReceiveProps(nextProps) {
    if(nextProps.UI.errors){
      this.setState({ errors: nextProps.UI.errors });
    }
  }

to this:

static getDerivedStateFromProps(props) {
    if (props.UI.errors) {
      return {
        errors: props.UI.errors
      }
    }
  }

you could keep using the first function above but would need to change it into UNSAFE_componentWillReceiveProps
