```js
db.cachedResponsesBlue.aggregate([
{
$match: {
"details.copied_from_artifact": {"$exists": false},
"details.cause_exception": {"$exists": true},
},
},
{
$group: {
_id: {
error_code: "$error_code",
cause_exception: "$details.cause_exception",
},
count: {
$sum: 1
},
},
}, {
$sort: { count: -1 }
}
]);
```

Start with the reported aggregation over db.cachedResponsesBlue and review how error_code and details.cause_exception are recorded. Determine which high-frequency errors require follow-up; the issue does not name files, tests, or a concrete change, so completion criteria need to be clarified before implementation.
