Description

Data for reproduction:

{
     "config": [
         [],
         [ "a string" ]
     ]
}

select flatten(config) as flat from cp.`/store/json/null_list.json`

This was carved out of a larger use case that was failing, so in the course of coming up with a minimal reproduction I fixed the bug. I will be posting a patch shortly.
