ClickUp Trigger - “Webhook configuration already exists” error after 2-3 executions

[Ricsy]

The ClickUp Trigger node consistently fails with error Bad request - Webhook configuration already exists after 2-3 successful executions, making it unreliable for production use.

To reproduce

1. Create ClickUp Trigger with task.updated event and List ID filter
2. Test workflow 2-3 times - works correctly
3. Subsequent executions or workflow activation fails with webhook duplicate error

Tested configurations:

ClickUp OAuth App authentication
Direct API Key authentication
• Both authentication methods produce identical behaviour!

The Clickup trigger is using webhooks under the hood and the error sounds like n8n is trying to register a webhook URL that already exists.

Same issue, when I create a ClickUp trigger or update it (add or delete the events), the trigger fails, which also happens after running it successfully a couple of times.

Using n8n cloud version 1.115.3

For me it’s self hosted, but I believe it’s the same.

Please fix it!
