iPA installed but cannot launch on iphone


I am trying to launch .ipa through appium in my iphone. I can see App installing in device, but beforehand no web driver app is installed.
Capabilities I have used are :
“platformName”: “iOS”,
“platformVersion”: “15.1”,
“deviceName”: “iPhone”,
“udid”: “00008101-001564-----------”,
“app”: “my app ipa file path.ipa”

I am getting below error :

Encountered internal error running command: Error: Unable to start WebDriverAgent session because of xcodebuild failure: An unknown server-side error occurred while processing the command. Original error: Could not proxy command to the remote server. Original error: socket hang up Make sure you follow the tutorial at https://github.com/appium/appium-xcuitest-driver/blob/master/docs/real-device-config.md. Try to remove the WebDriverAgentRunner application from the device if it is installed and reboot the device.

Please help me out to resolve this issue. I am in urgent need.


Did you complete wda build for real device?
