unbridled-41 opened a new issue, #5953:
URL: https://github.com/apache/rocketmq-dashboard/issues/5953
### Studio Version
branch: `rocketmq-studio` @ `7e7aa344` (the revision verified; the branch is
based on it)
deployed as: not required to reproduce
### Runtime Environment
Reproduced with the frontend tests (`cd web && npx vitest run
src/pages/instance/__tests__/MessagePageAsyncState.test.tsx`).
### Connected RocketMQ Cluster
Any instance whose trace provider is not configured or fails; the same
applies while the request is still in flight.
### Describe the Bug
The Trace and Verify tabs render the same payload - `handleModalTabChange`
fetches it on entering either - but only the Trace pane renders that request's
state:
```tsx
// trace tab
{traceLoading ? <Text>{t('messagePage.loadingTrace')}</Text>
: traceError ? <Alert type="warning" message={traceError} />
: traceData?.nodes?.length ? ... :
<Text>{t('messagePage.noTraceData')}</Text>}
// consumer (Verify) tab
<Table dataSource={traceData?.consumerStatus?.map(...) || []} ... />
```
A failed or pending trace request therefore renders antd's empty-table
placeholder on the Verify pane, which reads as "no consumer group consumed this
message" - the opposite of the truth - and the only way to see the error is to
switch tabs. The change that added the fetch for this tab (#4910) did not bring
the request state along.
### Steps to Reproduce
1. Point Studio at an instance whose trace provider is unavailable.
2. Open a message's detail, select the 验证 tab.
3. The consumer table is empty with no error and no loading state.
### What Did You Expect to See?
The same loading/error presentation the Trace tab shows for the same request.
### What Did You See Instead?
An empty table that looks like a measured "no consumers".
### Evidence
- `web/src/pages/instance/message.tsx` (the two tab children,
`handleModalTabChange`).
- `cd web && npx vitest run
src/pages/instance/__tests__/MessagePageAsyncState.test.tsx -t 'verify tab'` -
fails before the fix.
### Impact
The delivery-verification view reports "nothing consumed this message" when
the data simply could not be loaded.
### Acceptance Criteria
- The Verify pane renders the same loading text and error alert as the Trace
pane, with a regression test.
