Failed to create thread

Error message

Failed to create thread

What it means

continueInThread calls WorkspaceThread.new(workspace) to create the thread that will hold the run's response; if that helper returns a truthy `message` (its error channel), this throw fires with that text or 'Failed to create thread' as fallback. The workspace upsert succeeded, but the workspace_threads insert failed. The actual failure reason is the threadError text returned by WorkspaceThread.new.

Solutions

1. Read the threadError text in server logs - it carries the underlying Prisma/native error
2. Verify the workspace_threads table exists and migrations are current
3. Check database health, permissions, and connection limits
4. Retry the operation once the database is healthy - the workspace upsert is idempotent

try {
  await ScheduledJobRun.continueInThread(runId);
} catch (err) {
  if (/Failed to create thread/.test(err.message)) {
    // workspace upsert succeeded but the thread insert failed - retry once DB health returns
    return res.status(503).json({ error: 'Thread creation failed, retry shortly' });
  }
  throw err;
}

When it happens

Trigger: Prisma insert failure on workspace_threads (dropped connection, constraint violation, missing table after skipped migrations); the workspace object passed in is missing fields the thread creator expects.

Common situations: Transient DB outage mid-operation; instance upgraded without migrations; disk/connection limits hit exactly between the workspace upsert and thread insert steps.
