### 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: `1ef5d860` (upstream tip at the time of the report) deployed as: built from source ### Runtime Environment Verified by code tracing and unit tests on `rocketmq-studio` @ `1ef5d860` (vitest for `web/`, JUnit for `server/`), not against a specific browser or deployment. ### Connected RocketMQ Cluster Not cluster-specific: the defect lives in the code path and reproduces on any deployment where the trigger condition below holds. ### Describe the Bug Instance creation is check-then-act: `requireUniqueInstanceName` runs before the insert without any lock, and the `uk_instance_name` unique-key violation from a racing create is not translated. Only the cloud-credential foreign key case is mapped. ### Steps to Reproduce 1. Two tabs (or a retry racing a slow first submit) POST `/api/instances/create` with the same instance name. 2. Both pass `requireUniqueInstanceName`; the first insert wins. 3. The second request returns an opaque 500 internal error instead of the duplicate-name error. ### What Did You Expect to See? The losing create returns the same duplicate-name error as the sequential case so the UI can surface an actionable message. ### What Did You See Instead? A raw 500 for a routine duplicate-name collision. --- Fix PR: #4936 --- Re-submission: the original report (#4937) was closed by the stale bot after 7 days without triage activity, and GitHub now rejects reopening items in this repository.
