Error: Unrecognized node type: n8n-nodes-base.perplexity

Describe the problem/error/question

I’ve created an agentic workflow including the brand new Perplexity AI tool.
It works fine when tested with the Chat trigger inside n8n (self-hosted).
But when using the public web chat or any external trigger (e.g. via a Webhook),
the workflow fails.

What is the error message (if any)?

Workflow execution had an error
Error: Unrecognized node type: n8n-nodes-base.perplexity

Please share your workflow

I have SOLVED this issue by redeploying the WORKER on n8n, which wasn’t up to date. All good now.

Hi @callmefred,

How did you redeploy the Worker on n8n? Simply running docker compose down and up again or what did you do?

I am looking forward to hear from you as I struggle with a similar issue at the moment: N8N_Runners: Unrecognized node type: n8n-nodes-base.googleCalendarTool .

On Railway I simply clicked on ‘Redeploy’.
