Hello, Dear developers!

Driver reads array elements less than two incorrectly.

1. I have this code (which selects array of TEST_CASES from collection):

auto collectionName = CollectionCnst::VARIANT;
auto collection = db.collection(collectionName);
auto doc = bsoncxx::v_noabi::builder::basic::document{};
doc = bsoncxx::v_noabi::builder::basic::document{};
doc.append(kvp(ID, bsoncxx::oid(ourVariantId)));
auto cursor = collection.find_one({doc});
if (cursor->view().length() == 0) {
   // not found
   throw std::exception();
}
// select testCase's
auto testCases = cursor->view()[FieldCnst::TEST_CASES].get_array();
return testCases.value;

2. I want to iterate through it (foreach loop):

for (auto &testCase: testCases) {

  // do smth

}

3. If I have 1 element in collection, loop don't invokes no one time. If I have two elements, it invokes 1 time. If I have three or more array elements, it invokes exactly through all elements.
