 Double check the MongoDB query above for common mistakes, including:
 - Missing content in the aggegregation pipeline
 - Improperly quoting identifiers
 - Improperly quoting operators
-- The content in the aggregation pipeline is not valid JSON
-
+- The query must be using pymongo syntax, so make sure the syntax is correct.
+Example: 
+```python
+db.CollectionName.aggregate([
+    {{ "$match": {{ "field": "value" }} }},
+    {{ "$group": {{ "_id": "$field", "count": {{ "$sum": 1 }} }} }},
+    {{ "$sort": {{ "count": -1 }} }}
+])
+```
 If there are any of the above mistakes, rewrite the query. If there are no mistakes, just reproduce the original query.
 
 Output the final MongoDB query only.
