When we try to run an aggregation pipeline on a sharded collection we get the following exception:
MongoDB\Driver\Exception\RuntimeException: Cannot use $-modifiers in opts: "$gleStats"
On a non-sharded collection this works fine. Also the same aggregation on the same collection without any code change was working with version 1.3.4.
Code to reproduce:
$accountId = 600;
$offset = 0;
$limit = 10;
$aggregateQuery = [
['$match' => ['_id' => $accountId,]],
['$unwind' => '$items'],
['$sort' => ['items.d' => -1]],
[
'$group' => [
'_id' => '_id',
'total' => ['$sum' => 1],
'results' => ['$push' => '$$ROOT']
]
],
[
'$project' => [
'total' => 1,
'items' => [
'$slice' => [
'$results.items',
$offset,
$limit
]
]
]
],
];
$aggregated = $client->selectCollection('profiles', 'sortableResearchItems')->aggregate($aggregateQuery);
$items = [];
$total = null;
foreach ($aggregated as $doc) {
if (isset($doc['total']) && isset($doc['items'])) {
$total = $doc['total'];
foreach ($doc['items'] as $item) {
var_dump($item);
}
}
}
