Hello there.
I checked it out, and the Sell Items 'Asid' ability is missing for Granary buildings. Unfortunately, items dynamically added through triggers require such ability. Also, I added the ability 'Asid' through a trigger and made sure it's permanent to prevent potential morphing/upgrade effects removing the ability from the building.
Here's the test map:
