当我运行时出现以下错误npm run test：

jest-haste-map: Haste module naming collision: {{name}}
  The following files share their name; please adjust your hasteImpl:
    * <rootDir>/packages/some-package/templates/js/package.json
    * <rootDir>/packages/some-package/templates/ts/package.json

我的jest.config样子

module.exports = {
  collectCoverage: true,
  setupFiles: ['<rootDir>/jest.setup.js'],
  preset: 'ts-jest',
  testEnvironment: 'jsdom',
  collectCoverageFrom: [
    '<rootDir>/packages/**/__tests__/**/*.ts',
    '!<rootDir>/packages/**/templates/**/*.ts',
  ],
  testMatch: [
    '<rootDir>/packages/**/*.test.ts'
  ],
  transform: {
    '^.+\\.js?$': '<rootDir>/node_modules/babel-jest'
  },
  testPathIgnorePatterns: [
    '/node_modules/',
  ],
  coveragePathIgnorePatterns: [
    '/node_modules/',
  ],
  projects: [
    '<rootDir>/packages/*/jest.config.js'
  ]
};

不确定警告是什么，以及如何解决它。

我在使用嵌入式 Java API 的 Cypher 查询中使用 IN 运算符时遇到问题。您似乎无法将 IN 运算符与子句中检索到的实体以外的标识符一起使用start。

例如，这是我的查询：

start n=node(someLongNodeId) 
match n--m 
where m.gnid? IN [\"someStringId\",\"otherStringId\"] 
return m

在过滤 的属性时，我可以使用 IN 运算符，但当我执行上述查询并尝试调用从 返回的n值时，它会失败并出现以下异常：hasNext()IteratorcolumnAs("m")
