URL: https://github.com/apache/superset/issues/45638#issuecomment-6524018890
### Root Cause Analysis & Solution
In
`superset-frontend/packages/superset-ui-core/src/components/ListViewCard/ImageLoader.tsx`,
thumbnail requests are made using native `fetch`:
```typescript
fetch(src, { credentials: 'same-origin' })
```
When Superset is hosted under a subpath behind a reverse proxy (e.g.
`SUPERSET_APP_ROOT = "/analytics"`), relative URLs such as
`"/api/v1/chart/1/thumbnail/..."` do not include the application root prefix,
resulting in HTTP 404 responses for card thumbnails.
#### Solution
Prepend the configured application root by composing the endpoint URL
through `SupersetClient`:
```typescript
import { SupersetClient } from '@superset-ui/core';
const url = src.startsWith('http') ? src : SupersetClient.getUrl({ endpoint:
src });
fetch(url, { credentials: 'same-origin' })
```
Verified with unit tests in `ImageLoader.test.tsx` and committed to branch
`fix/community-unanswered-issues` (commit `2d8a057b7b6`) at
https://github.com/FrancescoCastaldi/superset/tree/fix/community-unanswered-issues.
