SyntaxError: Unexpected identifier jest & babel 7 & react-native 0.56

After upgrading react native version to 0.56, I could not run my tests. I was testing my app before upgrade.

I use node 10.9.0.

I get SyntaxError: Unexpected identifier error.

Details in below. Can you help me, please?

This is my devDependencies.

"@babel/core": "^7.0.0",
"@babel/plugin-proposal-optional-chaining": "^7.0.0",
"babel-core": "^7.0.0-bridge.0",
"babel-jest": "^23.4.2",
"babel-preset-react-native": "^5.0.2",
"enzyme": "^3.3.0",
"enzyme-adapter-react-16": "^1.1.1",
"enzyme-to-json": "^3.3.4",
"jest": "^23.4.2",
"react-addons-test-utils": "^15.6.2",
"react-dom": "^16.4.2",
"react-test-renderer": "^16.4.2",
"regenerator-runtime": "^0.12.1",
"sinon": "^6.1.5"

I configured the jest in this way.

"jest": {
  "preset": "react-native",
  "snapshotSerializers": [
    "enzyme-to-json/serializer"
  ],
  "setupTestFrameworkScriptFile": "<rootDir>/setupTest.js"
} 

.babelrc

{
  "presets": ["react-native"],
  "plugins": [
    "@babel/plugin-proposal-optional-chaining"
  ]
}
