addcyclic: TypeError: invalid indexer array

[am-thyst]

lon = dataset.longitude
lat = dataset.latitude
print(dataset.shape)
(241, 480)
print(lon.shape)
(480,)
print(lat.shape)
(241,)

fig = plt.figure()
ax = fig.add_axes([0.1,0.1,0.8,0.8])
m = Basemap(projection='cyl',llcrnrlat=-90,urcrnrlat=90,\
            llcrnrlon=-180,urcrnrlon=180, resolution='c')

dataset, lona = addcyclic(dataset, lon)
TypeError: invalid indexer array, does not have integer dtype: array([slice(None, None, None), slice(0, 1, None)], dtype=object)

I can't understand why I'm getting this TypeError?

This is not a fully self-contained example. It would also be useful to know which version of basemap you are using, and where you installed it from. Also, could you include the full traceback, please?

@WeatherGod It says my version of Basemap is 1.0.8.dev0, I think I saw that there is a 1.1.0? But conda says it is already up to date. I used conda-forge to install it. Here's the full traceback:

Ah, you are using xarray.DataArray objects. They don't behave quite like numpy arrays. Try converting them into numpy arrays before passing them into addcyclic. This is usually done by accessing the DataArray's .values attribute.

When calling conda update on a package that came from conda-forge, you should specify -c conda-forge. The basemap that is in the default channel hasn't been updated in forever (I have no control over that).
