Critical platform bug: Webhook nodes completely broken

Questions
1

Instance: bulechip.app.n8n.cloud
Plan: Pro

Error: Cannot read properties of undefined (reading ‘execute’)

Symptoms:

  • ALL workflows with Webhook nodes are non-functional
  • Cannot activate any workflow with Webhook node
  • Test mode doesn’t work
  • Listen for test event doesn’t respond

Other workflows (e.g., Refax) work normally.

Based on community reports, this is a platform-level issue
with corrupted n8n-nodes-base modules that requires
server-side intervention.

This is blocking all webhook-based automations.
Please prioritize urgent resolution.

Thank you

Hey - that “Cannot read properties of undefined” error on Webhooks is a known issue that usually points to a corrupted node module on the instance side. A few things to try:

1. **Deactivate and reactivate** - turn off the workflow, remove the Webhook node, save, then add it back fresh

2. **Clear browser cache** - sometimes the UI gets stuck with old node definitions

3. **Contact n8n support** directly with your instance URL (bulechip.app.n8n.cloud) and the workflow ID - they can force a module reload on their end which usually fixes it immediately

lmk if the first two don’t work - if not, support should be able to sort it fast since they can see the logs on the server.
