Hey @KutnerUri @Eliav2 ,

Any updates on this ? I am also experiencing it.

[DiaconuDan]

Meanwhile, I did not figured out the fix but did a workaround by disabling XArrows only in testing enviroment ( enabling it outside of testing enviroment basically )

{process.env.JEST_WORKER_ID === undefined && <ComponentWithXarrow > }

[KutnerUri]

I don't remember how I got around this.

Any update on this?

I get the same error using Jest and React testing library with TypeScript. Any updates?

[maxPiroddi]

Seems to still be no updates on this one...

For the time being, I have been working around it similar to DiaconuDan

{process.env.NODE_ENV !== 'test' && <Xarrow ... />

But definitely not an ideal solution!

[robertpin]

I was able to bypass it by mocking the component (I prefer not to conditionally render it based on the NODE_ENV).

jest.mock('react-xarrows', () => {
  return {
    __esModule: true,
    default: () => <span />,
    useXarrow: () => null,
  };
});
