Can not run Python Code Nodes in n8n 2.0. It seams n8n and Task Runners do not comunicate

Questions
1

I did not find an oficial compose.yaml to run n8n 2.0.0 plus TaskRunners plus Postgres plus Redis plus Caddy. With the help of AI tried several fixes for the problem. My Code Node in Pythoncontains only a return for JASON, it is the second node of 2. When it starts, keeps running but do not finish. It seams n8n and the TaskRunners do not communicate.

Describe the problem/error/question

What is the error message (if any)?

Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

This documentation was written before v2 released, but it is about the external mode, which became mandatory for V2:

Thank you very much !
I used the exact compose.yaml file from documentation you referenced.
Executed: same problem as always:

  • Code in Python (Beta) - ok
  • Code in Python (Native)(Beta) - code block does not end

Changed n8n to image “n8nio/n8n:2.0.0”
Same problem:
