We had a problem where a missing requested field on any database document would lead to an internal error in the engine. It turns out that in
$replaceWith
stages fields with missing values are silently omitted from response documents.This change adds
$ifNull
checks which insertnull
values in such cases.$ifNull
checks for either null or missing values, and the checks are written to put in an explicitnull
value in either case.Thankfully I was able to record a macro to help update the test cases!
