Unexpected token 'export' for >v3

Hi, I tried to understand for a very long time, but I ran out of ideas. After updating to version 3, tests began to fall with this error, in the place where I call the Api class. The project includes a dependency that was generated using swagger-typescript-api, everything was fine on version 2. Any idea why this is happening? Thanks

Test suite failed to run

    Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/en/ecmascript-modules for how to enable it.
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

@js2me Thanks for the help. You pushed me in the right way. jest.config.json

"transform": {
    "^.+\\.svg$": "<rootDir>/test/transform/svg.js",
    "^.+\\.ts$": "babel-jest",
    "\\.js$": "ts-jest",
    ".*\\.(vue)$": "vue-jest"
  },
"transformIgnorePatterns": [
    "node_modules/(?!@myApi)"
  ],

these lines are needed

"\\.js$": "ts-jest",
"transformIgnorePatterns": [
    "node_modules/(?!@myApi)"
  ],
