Failed to delete all chat sessions

Error message

Failed to delete all chat sessions

What it means

ChatService.deleteAllSessions rethrows this after logging when the bulk deletion of every chat session (and their messages) fails at the database level. This is a destructive admin operation, so any DB error — connection loss, lock timeout, FK restriction — aborts the whole wipe.

Solutions

Check logs for '[ChatService] Failed to delete all sessions: <cause>'
Ensure FKs are ON DELETE CASCADE, or wrap in a transaction that deletes chat_messages first
Retry when the system is idle to avoid lock contention
Verify DB health/connectivity before the admin wipe action

Example fix

// before
await ChatSession.truncate(true) // or bulk delete that hits FK restrictions

// after
await db.transaction(async (trx) => {
  await ChatMessage.query({ client: trx }).del()
  await ChatSession.query({ client: trx }).del()
})

Defensive patterns

Strategy: try-catch

Validate before calling

if ((await ChatSession.query().count('* as total'))[0].total === 0) return // nothing to wipe

Try / catch

try { await chat.deleteAllSessions() } catch (e) { if (e.message === 'Failed to delete all chat sessions') { confirmAndRetryOnce(); return } throw e }

Prevention

Require explicit confirmation for destructive wipes and run them at low-traffic times
Delete child tables in a transaction before the parent wipe
Verify FK cascade behavior in a staging DB before enabling the feature
Check DB connectivity and lock activity before issuing bulk deletes

When it happens

Trigger: Invoking 'delete all sessions' while the DB rejects the bulk delete: FK constraints without CASCADE, lock contention from active chat transactions, or the DB going away mid-statement.

Common situations: A schema where chat_messages references chat_sessions with ON DELETE RESTRICT/NO ACTION, long-running chat requests holding row locks during the wipe, or a DB restart/failover during the operation.
