Hey all I am just trying to get a simple test running and I keep running into this error after running "yarn test" which is using jest.

Plugin 0 specified in "/Users/Documents/Dev/appname/node_modules/babel-preset-react-native/index.js" provided an invalid property of "default" (While processing preset: "/Users/Documents/Dev/appname/node_modules/babel-preset-react-native/index.js")

Here is my package.json, what am I missing, im sure its a configuration issue and not a test issue.

{

  "name": "appname",

  "version": "0.0.1",

  "private": true,

  "rnpm": {

    "assets": [

      "resources/fonts"

    ]

  },

  "scripts": {

    "start": "node node_modules/react-native/local-cli/cli.js start",

    "test": "jest"

  },

  "dependencies": {

    "axios": "^0.18.0",

    "lodash": "^4.17.10",

    "react": "16.4.1",

    "react-test-renderer": "16.4.1"

  },

  "jest": {

    "preset": "react-native"

  }

}

don't know if you solved that already but I had the same issue and I was able to make things work again with RN 0.56. I changed this:

"babel-preset-react-native": "^5",

to

"babel-preset-react-native": "4.0.0",

here's the full discussion around the issue: https://github.com/storybooks/storybook/issues/3897

if the above breaks your react-native env, another solution would be to install babel-bridge:

npm install babel-core@7.0.0-bridge.0 --save-dev
