Hi,
I'm trying to use extend function, but having issue with it. For a simple image I get this error:
Expected integer or object for extend but received [object Object] of type object.

I'm using latest version on Windows, node v12, npm v6.

My code is the following:

const img = await sharp(path);
    const resized = await img
      .resize(200, 200)
      .extend({
        top: 20,
        bottom: 20,
      })

Below is also a sample image. Any idea what might be wrong? Thanks!
