When a variant IDL type contains an array, it will generate code like this (from query_settings_gen.cpp, the indexHints field)
const BSONType variantType = element.type();
switch (variantType) {
case Array:
if (element.Obj().isEmpty()) {
std::uint32_t expectedFieldNumber{0};
const IDLParserContext arrayCtxt(kIndexHintsFieldName, &ctxt, ctxt.getTenantId(), getSerializationContext());
std::vector<mongo::query_settings::IndexHintSpec> values;
const BSONObj arrayObject = element.Obj();
for (const auto& arrayElement : arrayObject) {
[...elided...]
++expectedFieldNumber;
}
_indexHints = std::move(values);
The arrayObject is empty, so the "for" loop, all the code in it, the expectedFieldNumber, and 'values' are not useful. _indexHints will be set to an empty array every time.
