Describe the problem/error/question
After upgrading to n8n v2.2.3 (from v1.x), my workflows that use the Execute Command node no longer work: publishing fails and activation is impossible.
- When I click Publish, I get:
Problem activating workflow — The following error occurred on workflow activationWorkflow could not be published: Unrecognized node type: n8n-nodes-base.executeCommand
The same workflow worked fine on v1.x.
What I understand / what I’m looking for
- In v2, certain sensitive nodes are disabled by default (including Execute Command) and must be explicitly re‑enabled via configuration.
- I’m looking for the exact Docker settings to re‑enable only Execute Command (ideally without enabling other nodes), and the best practices when running workers (queue/scaling) to avoid version mismatch errors after an upgrade.
Questions:
- Can you confirm the v2 behavior (Execute Command node disabled by default)?
- What is the recommended Docker configuration to allow only this node (rather than enabling all of them)?
- Do I need to redeploy/update the workers explicitly to avoid the “Unrecognized node type” error when the main instance and workers run different image tags?
What is the error message (if any)?
Problem activating workflow
The following error occurred on workflow activation:
