Yeah... the `template` is special, it must exactly match what the function returns. In your case, it seems like you know the dimension order. So you can transpose the template object to that dimension order","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,893692903

Right now, my code wraps func in a another function that performs this transpose when needed.

Isn't it the case the order matters here because you are providing a template for `map_blocks` to follow? Would your code still work if you were to leave `map_blocks` to do the inference of the output dataset on its own as Deepak pointed out? From the code snippet you provided, it appears that `map_blocks` works without the template 

```python
In [10]: dac.map_blocks(func).load()
Out[10]: 
<xarray.DataArray <this-array> (y: 3, x: 2)>
array([[0, 3],
       [1, 4],
       [2, 5]])
Dimensions without coordinates: y, x

Does it work then? You can also not provide `template` in which case it will infer the right thing.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,893692903

Does this work with `return d`? Could you add the stack trace?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,893692903
