# Runbook: ADAPTER_DISABLED (`runbook://adapter/adapter-disabled`)

## Symptoms

- HTTP 500 with `error.code=ADAPTER_DISABLED`
- Code invoked an optional adapter (Kafka/Redis/Slack/Email) that is disabled in this deployment

## Diagnosis

- Check adapter name in log (`adapter_name` field)
- Review deployment config — which optional adapters are enabled?

## Action

- Enable the adapter in deployment configuration (env flag)
- Or update application logic to skip disabled-adapter paths

## Escalation

- Escalate to deployment team if adapter should be enabled but isn't
