An admin clicked "Grant admin consent" and the n8n Microsoft credential still fails. The grant was real; it just did not cover the app or the scopes n8n actually requests. Here is the Entra ID checklist that ends it.
n8n Error Workflows configured through Settings often silently never fire on real failures. Here are the five confirmed causes and how to check each one.

Queue mode is the first real scaling step for self-hosted n8n, but the docs hide a few sharp edges. This guide pulls the important requirements into one deployment checklist.
A practical production blueprint for RAG on Supabase and Next.js: schema design, HNSW indexing, hybrid search, reranking, streaming, evaluation, and cost controls.
A step-by-step n8n workflow that reads active clients from Notion, pulls completed ClickUp tasks and Toggl time entries, builds an HTML summary and leaves a Gmail draft per client for review before sending.
