Error message
Internal Server Error
What it means
The catch-all 500 for POST /workspace/:slug/thread/new. The handler calls WorkspaceThread.new, Telemetry.sendTelemetry, and EventLogs.logEvent; any unhandled exception in these (most commonly a database insert failure in WorkspaceThread.new) returns 500.

Solutions
- Inspect server logs for the exception message printed by console.error(e.message, e).
- Verify the workspace_threads table exists and matches the current ORM schema.
- Confirm database connectivity and available storage.
Defensive patterns
Strategy: try-catch
Try / catch
try {
const res = await api.post(`/workspace/${slug}/thread/new`);
} catch (e) {
if (e.response?.status === 500) {
// thread creation failed — check DB health, retry once
} else { throw e; }
} Prevention
- Ensure database migrations are complete before starting the server.
- Monitor DB connectivity and storage capacity.
- Log the server-side exception to correlate with client failures.
When it happens
Trigger: Database write error during thread insertion; schema drift (workspace_threads table missing or mismatched); a concurrent migration locks the table; disk full preventing the DB write.
Common situations: DB locked during a migration; storage full; ORM schema out of sync with the database after an incomplete upgrade.
