Cannot test async hook that throws/rejects error

[sashberd]

Hi
I have next hook implementation:

const useWidget = () => {
  const { sid: companyId } = useParams()

  return useApi(async () => {
    return await postRecommendations(
      {
        onSuccess: async (result) => {
         return result
        },
        onError: async (error: AxiosError) => {
          //return Promise.reject(new Error(error, 'widget error'))
         throw (new Error(error, 'widget error'))
        },
      },
      { companyId }
    )
  })
}

where useApi is overlap of useAsync hook and it returns function to execution and used like:

const {execute} = useWidget()

useEffectOnce(()=>{execute()})

and postRecommendations is simple axios api call

I was trying to write unit test for onError case:

it('should render useWidgetRecommendedActions hook and throw error', async () => {
   
    postRecommendationsSpy.mockRejectedValueOnce(error401ResponseMock)
    const { result } = renderHookWithProviders(
      () => useWidgetRecommendedActions(mockGlobalFilters as SelectFilterType),
      {
        preloadedState: {},
      },
      dashboardContext.DashboardContextProvider
    )
    await expect(act(async ()=>await result.current.execute())).rejects.toThrow()
  })
})

I get next error typed near the unit tests without any assertation fail:

Cannot read properties of undefined (reading 'indexOf')

I was trying also other approaches like:

 //     try{
    // await act(async ()=>{await result.current.execute()})
    //     }catch(error){
    //       expect(error).toEqual(error401ResponseMock)
    //     }

But I had same error

Moreover, I tried to return Promise.reject without luck with same error

I am using vitest v:2.0.0

If anyone has encountered a similar implementation and has successfully written unit tests for it, please share your solution with me.
