Looks like they wrapped SetGradientAlpha functionality into SetGradient, I believe the fix for this issue is to change line 148 to:

button.highlightBg:SetGradient("HORIZONTAL", CreateColor(1, 1, 1, 0.45), CreateColor(1, 1, 1, 0))

However, I then get an error at line 235 that I can't figure out.  Far as I can tell argument #3 is allowed to be nil so I don't know what it's complaining about.

8x bad argument #3 to '?' (Usage: local texture = self:CreateTexture([name, drawLayer, templateName, subLevel]))

arithmandar has fixed the addon. Check wowace comments.

I can't resolve the issue with CurseForge's auto-packaging at the moment, and I don't have the permission to upload release manually probably due to my permission is not owner.

So if you don't mind, you can go do WoWInterface to download the latest release.

You can download the updated version here: https://www.wowinterface.com/downloads/info5541-AtlasLootEnhanced.html
