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.
