Bug with Kafka

I’m encountering a very nasty bug with Kafka where he doesn’t get messages until you resave the process. The resave lets the unprocessed messages go further.

Here are the parameters of my N8N:

  1. PostgresDB
  2. Run in Queue mode
  3. 10 workers, 3 webhooks, and 1 master node

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:
  • n8n version: 1.61
  • Database (default: SQLite): PostgreSQL
  • n8n EXECUTIONS_PROCESS setting (default: own, main): default
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Docker-Swarm
  • Operating system: Ubuntu

Hi @Vladimir_Petrosov,

Tip for sharing your workflow in the forum

Pasting your n8n workflow


Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!


Thanks for posting! Are you seeing any errors in the n8n logs, if so could you maybe share those? If you could also share your workflow (or parts of it or a description of the workflow) that would be helpful too!

There’s a reported issue on Kafka trigger node although not sure if this is related to the one you’re experiencing. Queue Mode Fails · Issue #11124 · n8n-io/n8n · GitHub

It’s impossible to provide - it’s random, appears at any time in any flow. I can see from the logs in the process that Kafka gets nothing. And then, by resaving, it starts working.

Hi!

It wasn’t solved. This is the biggest problem with the N8N for me right now. I have processing built through you, and this morning, I found out that I haven’t written a transaction for management accounting in 8 days because the Kafka trigger failed again before resaving.
