Description

Bug description

In ChartErrorMessage.tsx, the error title displayed when a chart fails to render is defined as a plain string constant:

const DEFAULT_CHART_ERROR = 'Data error';

This string is never passed through t(), so it cannot be translated. Users in non-English locales always see "Data error" regardless of their language setting.

Files

superset-frontend/src/components/Chart/ChartErrorMessage.tsx line 35

Fix

Import t from @apache-superset/core/translation and wrap the constant: const DEFAULT_CHART_ERROR = t('Data error');

Research direction
The fix is straightforward: import the `t` function from `@apache superset/core/translation` in `superset frontend/src/components/Chart/ChartErrorMessage.tsx` (line 35) and wrap the string constant `'Data error'` with `t()` as shown in the issue description. No additional investigation needed beyond verifying the import path and ensuring consistent syntax.
