toBuffer Promise never fullfilled

[katagaStyle]

let transformer = sharp()
      .rotate()
      .png()
      .toBuffer();

transformer.then( ( outputBuffer: any ) =>
{
    console.log( 'buffer' );
} );

readableStream.pipe( transformer );

The Promise will never be fullfilled. Any ideas?

Hello, there's an example of Stream-in/Promise-out in the tests.

Perhaps there's an error that needs a catch?

@katagaStyle Were you able to make any progress with this?
