Here's where the error is triggered:
https://github.com/pydata/xarray/blob/f3794ab1a75560f797b824c8c2d434aa65e7dd7d/xarray/core/dask_array_ops.py#L69-L73

We should specify both `dtype` and `meta` in the `map_*` calls like this:

``` python
pushed = array.map_blocks(push, axis=axis, n=n, dtype=array.dtype, meta=array._meta) 
if len(array.chunks[axis]) > 1: 
	pushed = pushed.map_overlap( 
		push, axis=axis, n=n, depth={axis: (1, 0)}, boundary=""none"",
		dtype=array.dtype, meta=array._meta
)
```
