Thanks Jamie.

Yes it now fails here with maxNumObs=1 and xarray main.

It looks like self._chunks is wrong but I don't know why.

Thanks @JamiePringle . it works for me with maxNumObs=1 (I assume the problem is not sensitive to this?) and

dask : 2022.3.0 zarr : 2.10.3 numpy : 1.21.5 xarray: main

Can you try downgrading zarr to 2.10.3? Does it still fail for you with maxNumObs=1? I don't see a commit that would've fixed this on xarray main... And I don't think dask is involved here.
