I'm having trouble with an issue similar to issue googleapis/nodejs-vision#9

I have a base64 image string that I need to pass to vision.textDetection(), and nothing seems to work.

The issue that I've mentioned suggests the following:

Don't know if this should still be working for the most recent version, because this is what I'm doing:

const [textDetections] = await vision.textDetection(
     { image: {
         source: {
           content: imgBase64
      }
    }});

And this is what I'm getting:

{ Error: 3 INVALID_ARGUMENT: Request must specify image and features.

This is my base64 string (it seems fine):

Also tried the following:

const buffer = new Buffer(imgBase64, 'base64');
const arraybuffer  = Uint8Array.from(buffer).buffer;

const [textDetections] = await vision.textDetection({image: {
  // content: buffer           // <--- TRIED BOTH WITH BUFFER AND ARRAY BUFFER
  content: arraybuffer
}});

Nothing seems to work.

Also, the docs don't mention anything about it accepting a base64 string.
