checkDocument is not a function

[Wexx]

Trying to write my first tests with this tool (seems really neat), but I'm running into some issues recreating the example projects I've seen (mainly this one: https://github.com/zinserjan/webdriverio-example/blob/master/test/diff-test.js).

relevant package.json items:

"wdio-visual-regression-service": "^0.9.0",
"webdriverio": "^5.11.6"

Posting the configuration below, let me know if anything else helps.

var path = require('path');
var VisualRegressionCompare = require('wdio-visual-regression-service/compare');

function getScreenshotName(basePath) {
    return function(context) {
        var testName = context.test.title;
        var resolution = context.meta.width || context.meta.orientation || 'unknown';
        var browserVersion = parseInt(/\d+/.exec(context.browser.version)[0]);
        var browserName = context.browser.name;

        return path.join(basePath, `${testName}_${resolution}_${browserName}_v${browserVersion}.png`);
      };
}

exports.config = {
    runner: 'local',
    path: '/',
    specs: [
       // 'test/specs/basic.js',
        'test/specs/visualRegression.js'
    ],
    exclude: [

        compare: new VisualRegressionCompare.LocalCompare({

            screenshotName: getScreenshotName(path.join(process.cwd(), 'screenshots/screen')),
            diffName: getScreenshotName(path.join(process.cwd(), 'screenshots/diff')),

          }),

}
