Why do i get this error ?

I am making a VPN app using TunnelKit library. It doesn't connect so i checked macOS console app and saw the following errors. What could be the reason of my problem ?

'Value of NETestAppMapping in the Info.plist for com.melisaozturk.VPN is not a dictionary or is empty'

'Failed to create an NSExtension with type com.melisaozturk.VPN: (null)'

'com.melisaozturk.VPN[28472]: dropping a message because the current state is not "started" (0)'

'SyscallError: setpriority(PRIO_DARWIN_ROLE, 30100, 3): No such process'

'

Can't get most elevated app state from dictionary {

BKSApplicationStateExtensionKey = 0;

SBApplicationStateDisplayIDKey = "com.melisaozturk.VPN";

SBApplicationStateKey = 0;

SBApplicationStateProcessIDKey = 30100;

SBApplicationStateRunningReasonsKey = (

{

SBApplicationStateRunningReasonAssertionIdentifierKey = Resume;

SBApplicationStateRunningReasonAssertionReasonKey = 10000;

}

);

}
