As @Blacksmoke16 suggested here, I changed the #touch method to use #set_timestamps instead of trying to directly update the @updated_at attribute.
I couldn't get the test suite to run locally, however, I made a test project that duplicated the issue described here and on the Amber repo and changed the info for Granite to point to my forked version with the change here and amber successfully compiled and displayed the welcome page.

I think this is a success!
