Jest problem with flow types of AsyncStorage class - react-native

Question

I believe this is a setup bug, but I don't know what to do anymore, I tried a lot of stuff. We have an app setup and tests are failing with error:
src/__tests__/App.spec.tsx
● Test suite failed to run
SyntaxError: .../react-native/Libraries/Storage/AsyncStorage.js: Unexpected token, expected "," (31:19)
29 | */
30 | const AsyncStorage = {
> 31 | _getRequests: ([]: Array<any>),
| ^
32 | _getKeys: ([]: Array<string>),
33 | _immediate: (null: ?number),

This is the App.spec.tsx code:
import React from 'react';
import renderer from 'react-test-renderer';
import { App } from '../app';
it('renders correctly with defaults', () => {
const app = renderer.create(<App />).toJSON();
expect(app).toMatchSnapshot();
});
My jest.json:
{
"preset": "react-native",
"cacheDirectory": ".jest/cache",
"testRegex": "(/__tests__/.*|\\.(test|spec))\\.(ts|tsx|js)$",
"moduleFileExtensions": [
"ts",
"tsx",
"js"
],
"transform": {
"^.+\\.(js)$": "<rootDir>/node_modules/babel-jest",
"\\.(ts|tsx)$": "<rootDir>/node_modules/ts-jest/preprocessor.js"
},
"transformIgnorePatterns": [
"node_modules/(?!(jest-)?react-native|react-navigation)"
],
"testPathIgnorePatterns": [
"\\.snap$",
"<rootDir>/node_modules/",
"<rootDir>/lib/",
"./build"
],
"globals": {
"window": true
}
}
Is there any helpful information that I can provide? Is this an issue with flow-types, babel...? My .babelrc is really simple.
