iOS 16.1.1 runtime error: RB query for the extension process state failed

I am working on a project and getting a runtime error when running our app on some colleague's iPhone 11 device(iOS 16.1.1) :
[lifecycle] [u 68C8D161-6D2A-412E-A4F2-CEDE8D1C83EF:m (null)]
[*PRODUCT_BUNDLE_IDENTIFIER(MARKETING_VERSION)*] RB query for the extension process state failed with error: Error Domain=RBSServiceErrorDomain Code=1
"Client not entitled" UserInfo={RBSEntitlement=com.apple.runningboard.process-state,
NSLocalizedFailureReason=Client not entitled, RBSPermanent=false}
The [PRODUCT_BUNDLE_IDENTIFIER(MARKETING_VERSION)] is something like : com.companyName.AppName.Keyboard(1.0.10)
This error message is only appears when the customized keyboard is loaded,
and the keyboard is also part of app group
I've checked iOS16 release note, seems like nothing is relevant to this error, I'm not sure what is causing this error message?

Exception: ideviceinfo returned an error: ERROR: Could not connect to lockdownd, error code -17

I tried install flutter on my mac but these error always show up :
⢿Unhandled exception:
Exception: ideviceinfo returned an error:
ERROR: Could not connect to lockdownd, error code -17
can anyone help me?
I've tried many ways but the error always show up.
I think it is caused by having an iOS device plugged in to your computer. I had the same issue and it went away after unplugging my phone. You won't get this message if the device is plugged in and the computer is marked as a trusted device.

Trying to send an email through an iphone app and getting an error using MFMailComposeViewController in iOS 8

I imported the MessageUI.h class and implemented the function in MFMailComposeViewControllerDelegate.
I was following the tutorial on : http://www.appcoda.com/ios-programming-101-send-email-iphone-app/
I am currently using Xcode 6.0.1 and iOS SDK 8.0 to build and run the app on the simulator. The issue is:
On running the app in the simulator, I get the following error
2014-09-26 03:39:07.687 SendMessage[44465:2674263] Mail cancelled
2014-09-26 03:39:07.743 SendMessage[44465:2673753] viewServiceDidTerminateWithError: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "The operation couldn’t be completed. (_UIViewServiceInterfaceErrorDomain error 3.)" UserInfo=0x7fe873e01d30 {Message=Service Connection Interrupted}

Any suggestions on what should be done to get this working?
This is a known error in the simulator. It does not appear when you run on a device. So, try it on a device and if it runs normally, then you should be ok.

I am getting this error while running in device.
Couldn't register com.xxxx.appname with the bootstrap server.
Error: unknown error code.
This generally means that another instance of this process was already running or is hung in the debugger.Program received signal: “SIGABRT”.
Now i rectified this problem .I have posted answer also if anyone got this error follow my post..
Try this,
Deleteing the app, restarting Xcode, clean build, didn't do anything
--> restart your computer
--> restart the phone

Fatal error: Uncaught CurlException: 7: couldn't connect to host thrown in

Yesterday was fine, but today, suddenly, my web app report an error while accessing Facebook PHP API.
At first, the error was connection time out. So, I added the time in base_facebook.php, changed the variable
CURLOPT_CONNECTTIMEOUT => 10 into
CURLOPT_CONNECTTIMEOUT => 60
Now, my web app reports another error:
Fatal error: Uncaught CurlException: 7: couldn't connect to host thrown in xxx\src\base_facebook.php on line 972
Ah, I run my app on localhost in Windows (XAMPP 1.7.7).
For testing it, I also run the example codes from the newest facebook API in github.
I also have restarted my Apache server, and It still gives the same error.
This is probably a server configuration problem on your side.
Check whether the host has blocked the ports 80 and 443.
