ee.Image.index raises AttributeError on median-reduced image about eemont HOT 2 OPEN

Hi, @aazuspan!

You're totally right. The problem here is that after reducing an image it loses all its properties. Most eemont methods depend on the system:id property, so it is necessary to have it. Given this, here is a workaround:

s2 = ee.ImageCollection("COPERNICUS/S2_SR")
pt = ee.Geometry.Point([-122.276437, 44.803428])
img = (s2
    .filterBounds(pt)
    .filterDate("2020-01-01", "2020-01-30")
    # Using .first() instead would fix the problem
    .median()
    .copyProperties(s2.first(),["system:id"])
)

img = ee.Image(img).scaleAndOffset().spectralIndices("NDSI")

I will leave this issue open, maybe I can find a way to fix this in the future :)

Cheers!

Awesome, thanks so much for the quick workaround! :)
