Error: Unsupported image type

[JohnRobPeter]

Hi, is the element screen shot supported? I have this error each time I run the element comparison. *Note: it works fine for checkScreen

• Node.js version: v8.9.4
• NPM version: 6.9.0
• Browser name and version: Chrome 74.0.3729.131 (Official Build) (64-bit)
• Platform name and version: Windows 10
• Framework name and version: Protractor 5.3.1 (protractor-cucumber-framework)
• Plugin name and version: protractor-image-comparison 3.1.1

Config of the automation framework + plugin

plugins: [
        {
            // The module name
            package: 'protractor-image-comparison',
            // Some options, see the docs for more
            options: {
                baselineFolder: path.resolve(process.cwd(), './baseline/'),
                formatImageName: `{tag}-{browserName}-{width}x{height}`,
                screenshotPath: path.resolve(process.cwd(), './screenshots/'),
                savePerInstance: true,
                autoSaveBaseline: true,
                debug: true,
                // ... more options
            },
        },
    ],

Describe the bug AssertionError: expected promise to be fulfilled but it was rejected with 'Error: Unsupported image type' and the saved images is only 3bytes in size that is only header in there

To Reproduce

expect(await browser.imageComparison.checkElement(element(by.xpath('.//logo')), sourceName, { /* some options*/ })).toEqual(0)

Expected behavior An image should be saved the same way it is for checkScreen

Log Though the debug is enabled no real logs are shown in the console for this plugin
