Hi @KaiHotz Solution is already mentioned, just add this in the jest.config file:

transformIgnorePatterns: [ ‘node_modules/(?!react-formik-ui/)’ ],

[iPwnPancakes]

For those using react-scripts in CRA, replace the test script line with: "test": "react-scripts test --transformIgnorePatterns \"node_modules/(?!react-formik-ui/)\""
