n8n workflow execution failed¶
Loki detected workflow failure strings in n8n-r940 logs within the last 15 minutes.
Checks¶
- Grafana Explore:
{host="n8n-r940"} |= "execution failed" - n8n UI → Executions for failed run details
- Credentials (Google Sheets, Anthropic, Supabase bearer) still valid
Common causes¶
- Google OAuth token expired (reconnect Google Sheets credential)
- External API rate limits (Anthropic, Supabase, Buffer/Late inline token)
