Hello n8n Community,
I am running into a persistent issue on my n8n Cloud instance and am hoping someone can help. I am unable to use or add standard, built-in nodes like Read PDF and OpenAI, as they consistently produce an “Unrecognized node type” error.
This is preventing me from building or importing any workflows that use these common nodes.
My Environment Details:
n8n Version: 1.102.4 (Confirmed this is the latest stable version as of July 2025)
Hosting: n8n Cloud (official n8n hosting)
The Problem:
When I try to add a standard node like OpenAI or Read PDF to a new workflow, or when I import a workflow that contains these nodes, I immediately get the following error:
Problem running workflow
Unrecognized node type: n8n-nodes-base.readPdf
(Note: The error also occurs for n8n-nodes-base.openAi)
Troubleshooting Steps Already Taken:
Checked for Community Nodes: We initially thought the workflow might have a custom node, so we created a new version using only standard n8n nodes. The error still occurs.
Checked n8n Version: We thought the instance might be outdated. However, we have confirmed that our version, 1.10.4, is the current stable release.
Ruled out Docker Issues: We considered that it might be a corrupted Docker image, but this is not applicable as we are on the managed n8n Cloud service.
Based on these steps, it seems the issue is not with the workflow itself but with our specific cloud instance failing to load its own core nodes.
Could the n8n team please investigate our instance to see why it might be having this issue?
Thank you for your time and help!
