Failed to generate year in review

Error message

Failed to generate year in review

What it means

500 from GET /api/2025 (Year in Review). The handler generates the yearly summary; unlike its siblings it includes error.message, so the response tells you the actual generation failure (usually reading/aggregating a year of conversation data).

Solutions

1. Read the 'message' field of the 500 response — it carries error.message
2. Clear caches and retry the endpoint
3. Prune or archive very old/corrupt conversation files under ~/.claude/projects
4. If it consistently fails on one file, the message usually names it; remove/fix that file

const hasData = await fetch(base + '/api/conversations').then(r => r.ok);

try { return await getYearInReview(); } catch (e) { if (e.message) log(e.message); return generateClientSideFallbackSummary(); }

When it happens

Trigger: GET /api/2025 when the year-review generator throws — corrupt session files, missing timestamps in conversations, or resource exhaustion over a year of data.

Common situations: Very large conversation histories; sessions with malformed created_at fields; disk/read errors in ~/.claude/projects.
