start_with? for nil:NilClass undefined method [email protected]/src/commands/upload/utils.js

Question

I have built a react native app and have it working via expo and am using expo build:ios and expo upload:ios. On upload it crashes with undefined method 'start_with?' for nil:NilClass in the utils.js for expo.

Error: undefined method `start_with?' for nil:NilClass

Expo diagnostics:

Expo CLI 2.9.0 environment info:
    System:

      Shell: 3.2.57 - /bin/sh
    Binaries:
      Node: 10.15.1 - /usr/local/bin/node
      npm: 6.4.1 - /usr/local/bin/npm

    npmPackages:
      expo: ^32.0.0 => 32.0.4 
      react: 16.5.0 => 16.5.0 
      react-native: https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz => 0.57.1 
      react-navigation: ^3.0.9 => 3.1.4 
    npmGlobalPackages:
      expo-cli: 2.9.0

I have never uploaded an app before so I don't have any idea what the solution would be if its my code, the build, the software installed.
