Discord Node: Works with custom webhook but fails with n8n course webhook URL

[noumantechie]

Bug Description

Bug Description

Discord node works fine with my custom webhook URL but throws Cannot read properties of undefined (reading 'error') when using the n8n Level 2 course webhook URL.
What works: ✅ Custom Discord webhook
What fails: ❌ n8n course webhook URL

Error: Cannot read properties of undefined (reading 'error')

To Reproduce

1. Create workflow with Convert to File → Discord nodes
2. Configure Discord node with "Send a Message"
3. Test with custom webhook URL → Works
4. Test with n8n course webhook URL → Fails
5. See error in OUTPUT panel

Expected behavior

Both webhook URLs should work without errors.
