Cannot use ImageComparison on MacOS apps

See original GitHub issue

The problem

I’m developing tests for an app, which is rendered in Unity - this means I cannot simply locate elements. Therefore, I’m limited to using image recognition. This works great on Android, but when I try to use it on macOS desktop app, I get: org.openqa.selenium.UnsupportedCommandException: Could not find selector (post_appium_compare_images:data:) for path ‘/session/3aUyAV7O/appium/compare_images’.

The app is launched correctly, it’s at the time of looking for the image that I get this error.

Environment

Appium version (or git revision) that exhibits the issue: 1.17.1
Last Appium version that did not exhibit the issue (if applicable): N/A
Desktop OS/version used to run Appium: macOS 10.15.5 Catalina

Code To Reproduce Issue [ Good To Have ]

OccurrenceMatchingResult result = driver .findImageOccurrence(screenshot, loginPage.getRefImageBytes("email_field.png"), new OccurrenceMatchingOptions() .withEnabledVisualization() .withThreshold(0.7)); Assert.assertTrue(result.getVisualization().length > 0); Assert.assertNotNull(result.getRect()); result.storeVisualization(new File("occurrence_email.png"));
