You can upgrade to newer Jest that supports package exports or set a moduleNameMapper in jest.config.js like so

 moduleNameMapper: {
    '^nimma/fallbacks$': '<rootDir>/node_modules/nimma/dist/cjs/fallbacks/index.js',
    '^nimma/legacy$': '<rootDir>/node_modules/nimma/dist/legacy/cjs/index.js',
  },
