When running my managed workflow project (SDK 42), I get the above error right before the package builds,and I cannot figure out why. Below is my app.json file from this project:

{
  "expo": {
    "name": "App-Name",
    "slug": "App-Name",
    "version": "1.0.0",
    "orientation": "portrait",

    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },
    "updates": {
      "fallbackToCacheTimeout": 0
    },
    "assetBundlePatterns": [
      "**/*"
    ],
    "ios": {
      "supportsTablet": true,
      "infoPlist":{
  
      }
    },
    "android": {
      "adaptiveIcon": {
        "foregroundImage": "./assets/adaptive-icon.png",
        "backgroundColor": "#FFFFFF"
      },
      "permissions":[
        
      ],

    },
    "web": {

    }
  }
}
