**Expected behavior:**
I should be able to build and run the basic-setup example in the repo when using the latest master commit (8633375).

**Observed behavior:**
When I run `npm run render` with a blank Sketch document open, I get the error 

```
Warning: Failed prop type: Invalid prop `error` supplied to `RedBox`.
    in RedBox
Struct CGRect has no member named size
```

**How to reproduce:**
```
git clone https://github.com/airbnb/react-sketchapp.git
cd examples/basic-setup
npm install
npm run render
```

**Sketch version:**
45.2

**Other notes**
I can build the `colors` example project correctly.
