Why an n8n RSS Feed Trigger Fails to Run: A Practical Troubleshooting Checklist

·1 views

A common frustration with n8n RSS workflows is that the trigger appears set up correctly but produces no executions or runs with zero items. This guide offers a roughly fifteen-minute checklist, documented against self-hosted n8n 2.44.6 and not tested on n8n Cloud. Scheduled and polling triggers only fire in production when the workflow is published and active, since manual test runs do not confirm overnight behavior. Feed-level problems such as broken HTTPS, publisher blocks, login pages, feed format mismatches, or redirects can also make a working-looking trigger appear dead. Silent filters like lookback windows, duplicate removal, limits, and continue-on-error settings can likewise leave a digest empty without any visible error.

useSyncExternalStore: Why Snapshot Identity and SSR Initial Values Matter

An external store can notify subscribers without changing what useSyncExternalStore renders, because the hook needs a snapshot that differs by Object.is. In this experiment, mutating the same snapshot object and notifying listeners left the screen showing 0, while replacing it with a new object updated the display to 2. Checking only whether a notification was sent therefore misses the difference. The test also covered hydration, where the client's initial read must receive the server's value, passed through window.__BOOTSTRAP__, even though the client store started with a newer value. The author notes that the experiment did not test rerenders from unrelated updates, the update loop caused by returning new objects on every read, or subscription performance at scale.

UIDAI Unveils Lighter Sub-AUA/Sub-KUA Route for Low-Volume Aadhaar Users

On 29 September 2026, UIDAI announced five initiatives at Aadhaar Samvaad in Kolkata, including a new LITE framework for Sub-AUAs and Sub-KUAs. Sub-AUAs and Sub-KUAs access Aadhaar services through an existing AUA or KUA, which handles Yes/No authentication and e-KYC respectively. The LITE framework is intended to simplify and speed up onboarding for entities with lower authentication volumes, including government and eligible non-government bodies. Under existing rules, AUAs and KUAs need UIDAI approval before appointing a Sub-AUA or Sub-KUA, and they remain jointly liable for compliance. The article notes that UIDAI has not yet released full details of the LITE route, so regulated entities such as lenders and fintechs are advised to prepare while awaiting clarification.

Money Tracker app explains bill import without bank logins, using confirm-before-save

The developer of Money Tracker, an expense app for Android and iOS, describes its statement and bill import feature, which is available on the Premium tier. Users export a file such as a PDF or CSV from their bank or card issuer, then upload it to the app, which parses it into draft entries. Each draft must be reviewed and confirmed by the user before it is saved to their records. The developer stresses that the app never asks for bank credentials and does not maintain ongoing connections to accounts, unlike bank-sync services. The post presents this as a narrower, more controlled alternative to automatic open-banking sync.
