colorbar 'cmap' error

[khouakhi]

This example from the documentation of cartoee gives an error when adding cmap for the colorbar (but works when using custom palette)

# get an earth engine image
srtm = ee.Image("CGIAR/SRTM90_V4")
# vis 
visualization = {'min':-500,'max':3000,'bands':'elevation'}
bbox = [-180,-90,180,90]

# plot the map
ax = cee.getMap(srtm,cmap='terrain',
                region=bbox,
                visParams=visualization,
                dims=1000)
# add a color bar using cartoee
cb = cee.addColorbar(ax,loc='right',
                     cmap='terrain',
                     visParams=visualization)

ax.coastlines()
