I think that works as intended, although the error message could definitely be better.

Series is limited to 1D arrays, so we have to convert DataArray objects with more than one dimension using stack. If the object already has a MultiIndex this fails because we don't support da.stack(xy=['x', 'y']).stack(xyz=['xy', 'z']).

It's a pity because having a partial MultiIndex DataArray helps a lot if there are lots of combinations of x and y with NA values. My reason to transfort into a pandas object is that I need to groupby by 3 dimensions.

EDIT: I have found a strange workaround: da.stack(xy=['x', 'y']).to_dask_dataframe().compute()
