That looks like a Snowfakery/CCI bug, TBH.

Based on the traceback I believe a workaround is to run with the simpler generate_and_load_from_yaml command which is slower, simpler, and for the time being sometimes more reliable by virtue of its simpler code.

@prescod same issue with cci task run generate_and_load_from_yaml --generator_yaml datasets\PMM\pmm_1_program-service.recipe.yml --num_records 5 --num_records_tablename pmdm__Program__c
