# Example: Wallaby with TypeScript/Jest using TSX
Minimal demo for the Wallaby [issue #1306](https://github.com/wallabyjs/public/issues/1306).
## The issue
When used with Wallaby.js 1.0.59, this setup should reproduce the following
error in the `Wallaby.js Tests` panel in VS Code (1.16.1):
```
TypeError: Object prototype may only be an Object or null: undefined
at Object. src/Index.test.ts:1
```
This is most likely referring to the following code:
```tsx
@Component
class Index extends Vue { // <-- this line
public render(createElement: CreateElement): VNode | null {
```
## Differences from the original setup
In the original setup, the error would point to the `class` line in the module
that's being tested. In this setup, it points to the `import` statement in the
test module.
In this setup, the Wallaby.js status indicator shows 10 tests passing, whereas
in the original setup, it always shows 0 passing. Either way, it does not match
what Jest shows when run from the CLI.
