How to solve the error while connecting real iOS device with Appium server?

Hi…I’m opening an Application through Appium Server but I’m getting the error:

    An unknown server-side error occurred while processing the command. Original error: Unknown device or simulator UDID: '046e4469d6cb14ff57e378599bd4b1d09390472b'

{

“platformName”: “iOS”,

“deviceName”: “iPad”,

“automationName”: “XCUITest”,

“udid”: “046e4469d6cb14ff57e378599bd4b1d09390472b”,

“bundleId”: “com.***”,

“app”: “/Users/***/***.ipa”

}

Thanks.
