flutter permission_handler archive failed

Question

I am using permission_handler ^9.2.0 in my project https://pub.dev/packages/permission_handler

When I try to archive the iOS project it failed with error

Command PhaseScriptExecution failed with a nonzero exit code.

The instructions in the page says I have to modify the Pod file. And as far as I can see I have done it correctly with the permissions I need to use.

Can anyone point to what I did wrong here?

Only line that was different to what was in the webpage is;

flutter_additional_ios_build_settings(target)

# Uncomment this line to define a global platform for your project
# platform :ios, '11.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
