  • .. oo:: LISTS_AS_STRING_JSON
    :choices: YES, NO
    :default: NO
    :since: 3.12.1

    Whether lists of strings/integers/reals should be reported as String(JSON)
    fields rather than String/Integer[64]/RealList.
    Useful when null values in such lists must be exactly mapped as such,
    instead of being omitted (for lists of strings), or set to 0 (for list of
    boolean, integer or real).

Fixes #13448
