### Before Creating the Bug Report - [x] I have searched the [open issues](https://github.com/apache/rocketmq-dashboard/issues) of this repository and believe that this is not a duplicate. - [x] This is a defect in RocketMQ Studio, not a usage question and not a defect in another Apache RocketMQ repository. - [x] I can reproduce this on the current `master` branch, or I have stated the exact version I am running below. ### Studio Version branch: rocketmq-studio git commit id: 7ce9a68215c4cd1c7025013d02135b43b6aa6ba1 deployed as: built from source (`cd web && npm ci && npm run build`) ### Runtime Environment OS: Windows 11 with WSL2 (Ubuntu 24.04.3 LTS) MySQL: 8.0.36, container from `deploy/docker-compose.yml` browser: Chrome 141 ### Connected RocketMQ Cluster Not involved: the defect is in the deliveries page's client-side filter loading, reproduced in Vitest with a rejected `listInstances`. ### Build Toolchain Node.js 20.19.0, npm 10.8.2 ### Describe the Bug `web/src/pages/ops/notificationDeliveries.tsx` loads the instance list for its instance filter with: ```js useEffect(() => { void listInstances() .then(setInstances) .catch(() => undefined); }, []); ``` The `catch` discards the failure. The selector renders `instances.map(...)`, so the user sees an empty dropdown: no error, no message, and no way to retry other than a full page reload. The visible result is indistinguishable from a deployment that has no instances registered, which is a different and much less likely fact. Every other load on the page reports its failure (`t('deliveries.loadFailed')`), so this is the one silent spot. ### Steps to Reproduce 1. Open the notification deliveries page while `GET /api/instances` fails (stop the backend, or make it return 5xx). 2. Open the instance filter. ### What Did You Expect to See The filter says it could not load its options and offers a retry, rather than presenting an empty list as a fact. ### What Did You See Instead An empty instance filter with no indication that anything failed. ### Additional Context I have a fix ready: PR #4700. ### Are You Willing to Submit a Pull Request? - [x] Yes, I am willing to submit a pull request. -- This is an automated message from the Apache Git Service.
