Undefined is not an object, ejected expo app.

[llanginger]

Hi guys,

I'm facing this same issue described in parts of #34 (with an ejected expo app). I have tried this with both a fairly complex app built with expo and newly-ejected as well as a completely fresh expo app. Same error in either case.

Steps to reproduce:

1: create-react-native-app [name] and cd into [name]
2: yarn eject, choosing expokit
3: yarn add blinkid-react-native and react-native link blinkid-react-native
4: update Podfile (Could there be some issue here?) as such;

platform :ios, '9.0'

EXPO_CPP_HEADER_DIR = 'ExpoKit'

target 'blinkid' do
  pod 'PPBlinkID', '~> 4.0.0'
  pod 'ExpoKit',
    :git => "http://github.com/expo/expo.git",
    :tag => "ios/2.5.10",
    :subspecs => [
      "Core",
      "CPP",
      "GL"
    ]

  pod 'React',
    :path => "../node_modules/react-native",
    :subspecs => [
      "Core",
      "ART",
      "RCTActionSheet",
      "RCTAnimation",
      "RCTCameraRoll",
      "RCTGeolocation",
      "RCTImage",
      "RCTNetwork",
      "RCTText",
      "RCTVibration",
      "RCTWebSocket",
      "DevSupport",
      "CxxBridge"
    ]
  pod 'yoga',
    :path => "../node_modules/react-native/ReactCommon/yoga"
  pod 'DoubleConversion',
    :podspec => "../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec",
    :inhibit_warnings => true
  pod 'Folly',
    :podspec => "../node_modules/react-native/third-party-podspecs/Folly.podspec",
    :inhibit_warnings => true
  pod 'glog',
    :podspec => "../node_modules/react-native/third-party-podspecs/glog.podspec",
    :inhibit_warnings => true


  post_install do |installer|
    installer.pods_project.main_group.tab_width = '2';
    installer.pods_project.main_group.indent_width = '2';

    installer.pod_targets.each do |target|

    if target.pod_name == 'ExpoKit'
      target.native_target.build_configurations.each do |config|
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'EX_DETACHED=1'
        
        # needed for GoogleMaps 2.x
        config.build_settings['FRAMEWORK_SEARCH_PATHS'] ||= []
        config.build_settings['FRAMEWORK_SEARCH_PATHS'] << '${PODS_ROOT}/GoogleMaps/Base/Frameworks'
        config.build_settings['FRAMEWORK_SEARCH_PATHS'] << '${PODS_ROOT}/GoogleMaps/Maps/Frameworks'
      end
    end


    if ['Amplitude-iOS','Analytics','AppAuth','Branch','CocoaLumberjack','FBSDKCoreKit','FBSDKLoginKit','FBSDKShareKit','GPUImage','JKBigInteger2'].include? target.pod_name
      target.native_target.build_configurations.each do |config|
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
      end
    end
    # Build React Native with RCT_DEV enabled
    next unless target.pod_name == 'React'
    target.native_target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'RCT_DEV=1'
    end

    end
  end
end

5: pod install (so far no errors)
6: copy example app to App.js, replacing license key with my generated key

Any help would be greatly appreciated - in an ideal world I would like to be able to include this in my product demos coming up next week, though it's the weekend so that's not where I'm setting my expectations!

Thanks in advance,

Hi @llanginger,

I created an app using expo and ejected it(expokit) and it runs as expected. I have used v4.2.0 of BlinkID but there should be no difference in the usage. Since you used cocoapods, see if you have git-lfs installed. Git-lfs might be the cause especially if this happens only on iOS. If you don't have git-lfs follow the instructions here.

Kind regards,
Jure
