Unknown type: ${v.type}

Error message

Unknown type: ${v.type}

What it means

The dlnews route maps each article body block by its `type`. The switch handles `list` and `image`; any other `v.type` hits `default` and throws a generic Error, which fails the whole item (and propagates out of the Promise.all). This is an internal parser-completeness gap.

Solutions

1. Find the new `type` value in the API response and add a rendering case.
2. Return an empty string in the `default` arm as a graceful-degradation stopgap.
3. Add a regression test that renders a payload containing every known block type.

Example fix

// before
//   default:
//       throw new Error(`Unknown type: ${v.type}`);
// after
//   default:
//       return '';

const HANDLED_BLOCK_TYPES = new Set(['list', 'image']);
function isHandledBlock(v: { type: string }): boolean {
  return HANDLED_BLOCK_TYPES.has(v.type);
}

function isHandledBlock(v: { type: string }): v is { type: 'list' | 'image' } {
  return v.type === 'list' || v.type === 'image';
}

try {
  renderBlock(v);
} catch {
  // unknown block — skip it, keep the rest of the article
}

When it happens

Trigger: dlnews adds a new content-block type (e.g. heading, quote, embed, video, gallery) that the switch does not handle.

Common situations: An upstream content-model change ships new block types; the error appears only on articles that use the new blocks.
