During the process of updating RN to 0.73. I am running into this issue on the app center ios pipeline.

Many people say that it is related to use_framework and that adding a pre_install with a explicit type to static library would fix it but it did not for me. I am pretty sure that RNReanimated is what i need to target but am i wrong?

    pre_install do |installer|
     installer.pod_targets.each do |pod|
       if pod.name.eql?('RNReanimated')
         def pod.build_type
           Pod::BuildType.static_library
         end
       end
      end
    end

• I have also tried removing use_modular_headers!
• upgrading react-native-video but I end up getting a different error.
• upgrading react-native-reanimated
• adding RNReanimated to the ImageNotification target like below

target 'ImageNotification' do
  platform :ios, '14.0'
  pod 'Firebase/Messaging'
  pod 'Iterable-iOS-AppExtensions'
  pod 'RNReanimated'
end
