This actually caused by the missing args like `input_core_dims`, `exclude_dims`, etc.

Anyway, this one works well:
```
res = xr.apply_ufunc(reduceat_np,
                     dask_data,
                     bins_reduceat[:5],
                     input_core_dims=[['x'], ['new_x']],
                     exclude_dims=set(('x',)),
                     output_core_dims=[['new_x']],
                     dask=""parallelized"",
                     output_dtypes=[data.dtype],
                     dask_gufunc_kwargs={'allow_rechunk': True},
                    )
res.compute()
