React-sketchapp: TypeError when rendering basic example

[apexskier]

Expected behavior:

Following the basic example instructions works

Observed behavior:

When I run the render task, Sketch opens, but the following error

TypeError: null is not an object (evaluating 'context.document.currentPage')
line: 9246
column: 114

This should be way clearer, sorry - you need to have a new Sketch document open when you call render.

We've asked the Sketch devs to help us out on this but haven't got a timeline thus far :(

Great, thanks for the info!

Will it be better to verbose an info indicating the user a new sketch doc is required ?
