Description
Hello,
I am using Next.js, and I have a problem when trying to test a component with react.createNode or react.createElement. The test cannot understand my component and displays errors. However, on all other components that do not use these features, the tests work fine. My environment:
"next": "14.0.1",
"typescript": "5.2.2",
"react": "18.2.0",
"react-dom": "18.2.0",
"@testing-library/jest-dom": "5.16.5"
"@testing-library/react": "14.1.2",
"@types/react": "18.2.14",
"@types/react-dom": "18.2.6",
"jest-environment-jsdom": "29.3.1",
"ts-jest": "29.1.0",
What I did:
Problem description:
Argument of type 'boolean' is not assignable to parameter of type 'ReactElement<any, string | JSXElementConstructor>'.ts(2345)
Parsing error: '>' expected.eslint
'ListPageActionBar' refers to a value, but is being used as a type here. Did you mean 'typeof ListPageActionBar'?

Research direction
No repository file, test, or minimal reproduction is named; start by reproducing the reported Next.js and TypeScript test case from the screenshots and dependency versions. Determine whether the failure is caused by ReactElement typing, JSX parsing, or test setup, then document a reproducible case and confirm the expected component test behavior.
