Explanation
The title "⚡️(metrics) paginate usage metrics view" matches the main change. The raw summary says MailDomainUsersMetricsApiView now returns paginated metric groups with a default limit of 10 and a maximum of 100, and the tests cover pagination behavior. The title is short, specific, and does not describe anything missing from the changeset. The title includes an emoji prefix, which the title guidelines call noise, but this does not change the assessment. No description or validation details were provided, but the title is still clear for a reviewer.

🟡 Minor · Skip domains whose grouping value is an object or array. · metrics.py:103
src/backend/core/api/viewsets/metrics.py:103
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick winSkip domains whose grouping value is an object or array.
With the default
SCHEMA_CUSTOM_ATTRIBUTES_MAILDOMAINof{}, a domain can store an object or array under the requested custom-attribute key. The grouping loop then uses that value as a dictionary key, which raisesTypeErrorand fails the request with a 500 before pagination.🐛 Suggested fix
if group_by_custom_attribute_key: group_value = domain.custom_attributes.get( group_by_custom_attribute_key ) + # Object and array values cannot be dictionary keys. + if isinstance(group_value, (dict, list)): + continue else: group_value = domain.name🤖 Prompt for AI Agents

- Line 71: Update the guard on group_by_custom_attribute_key to reject
numeric-looking keys so Python grouping and Django’s custom-attribute lookup use
compatible key semantics; add a test with an object whose custom attribute key
is "0" to verify the key is rejected and the metrics path does not raise
KeyError.

🟡 Minor · Group custom-attribute values by JSON type, not by Python equality. · metrics.py:99-122
src/backend/core/api/viewsets/metrics.py:99-122
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winGroup custom-attribute values by JSON type, not by Python equality.
Python treats
Trueand1as the same dict key, and1and1.0as the same key too. The domain loop groups by the raw decoded value, so a domain withtrueand a domain with1share one group and one page slot. The metrics loop then overwrites the user count for that group. The database keeps the two values in separate rows, so one of the two user counts is lost.Suggested fix
