**Issue Evaluation**
Category: `bug` | Status: **Confirmed**
The reported JSON property mapping issue has been verified in
`DlqMessageRequest`.
**Root Cause:** The class exposes `topicName` field, but the frontend sends
`topic` as the JSON property. Jackson ignores the unmatched `topic` property,
causing the resend service to receive a null topic.
**Impact:** Batch DLQ resend fails silently because the topic information is
lost during deserialization.
**Severity:** High — breaks a core feature (DLQ message resend) when using
the new frontend batch action.
**Suggested Fix:** Add `@JsonProperty("topic")` as an alias on the
`topicName` field, or add a separate `topic` field with proper mapping.
An automated fix proposal can be generated. Reply `/approve` to proceed with
