Unable to start application on this device: An unknown server-side error occurred while processing

I have problem with Mobile testing
My Appium’s version is 1.7.1, Android’s version is 8.0.0
Please help me


i found this error when executing existing test case. first, you may change appium log level to debug in Katalon>window>preferences>katalon>mobile. then, do clear data and clear cache in your app info from your mobile device if your apps has already installed before. Try and update your result.

make sure you do not have your app installed in your device. if you do, clear data and clear cache your app or uninstall it by yourself (this i have never tried)
