I'm getting an error "Error: Unrecognized node type: n8n-nodes-base.evaluationTrigger" while using n8n version 1.105.3

[adam_starta]

I’m encountering this error when trying to open or execute a workflow that includes the Evaluation Trigger node (n8n-nodes-base.evaluationTrigger). It appears that my workspace does not recognize or support this node.
I do not see a “Feature Previews” section in my workspace settings, so I suspect the AI Workflow Evaluation feature (which includes this node) is not enabled for my account.
Steps to Reproduce:
Import a workflow that includes an Evaluation Trigger node.
Attempt to open or execute the workflow.
Observe the error: Unrecognized node type: n8n-nodes-base.evaluationTrigger.

Describe the problem/error/question

What is the error message (if any)?

Please share your workflow

No workflow to share since the node itself is not detected by n8n hosted.

Hi there, are you using self host? have you update your n8n? have you activated the lincense key to get the community edition?

[adam_starta]

Hi, thank you for your response. Yes, I’m using self hosted and updated to the latest n8n version. I also have activated the license key. Aside from the evaluation node, I also noticed that even “merge” node is not working. It’s also showing unrecognized node type so some of the core nodes are not working.

Just for everyone’s knowledge. I resolved this by reinstalling everything.
