It was a bug in the documentation page but not in `rolling.construct`.

It should raise an error in this case, because for 2d rolling we need 2 dimension names,
```python
rolling_da = r.construct(x=""x_win"", y='y_win' , stride=2) 
```
I corrected the documentation and error message.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,675604714

I'm not sure what causes the error in `rolling_da.mean(""window_dim"", skipna=False) `

`self._mapping_to_list` should handle this problem. 
How can I get the details of this error?
I just saw the time-out error...
