Hello Railway Support,

I’m hosting an n8n instance on Railway, and I’ve been running into recurring errors in the logs. Please see the attached screenshots for reference.

The main issues I’m seeing are:

1. Webhook errors

   Received request for unknown webhook: 
   404 The requested webhook "POST <UUID>/webhook" is not registered.
   

   These keep repeating, even though I haven’t configured those webhooks explicitly.

2. Postgres checkpoint messages

   LOG: checkpoint complete: write XX buffers (...) 
   

   These are very frequent and I’m not sure if they’re expected or a sign of a misconfiguration with the Railway Postgres add-on.

Because of these issues, some workflows in n8n are not triggering as expected.

Could you please help me understand:

• Why these webhook errors are happening and how I can resolve them?

• Whether the Postgres checkpoint logs are normal on Railway or if something needs to be adjusted in my setup?

Thank you very much for your support!
