Appium setup issues

Trying to setup Appium with Android but keep getting errors. I have an APK manually installed to an actual device. I have followed the instructions on the error message with no luck.

My Desired capabilities are set to:

>   "appPackage": "com.XYZ.android",   "appActivity":
> "com.XYZ.android.homepage.HomePageActivity",   "platformName":
> "Android",   "deviceName": "Google Pixel 3a",   "udid": "99NBY3DL9K", 
> "automationName": "UiAutomator2",

Get this error:
