Hi,
I'm new to Custom Connectors - have got an Action working with Trello API but struggled with the Triggers.
I then tried just doing it with the example shown here: https://docs.microsoft.com/en-us/connectors/custom-connectors/create-webhook-trigger under "Create webhook triggers from the UI" and I'm getting the error code of:
Specified swagger failed validation: 'The operation is not valid, it must contain at least one response definition.'
Any ideas? My webhook response section looks like:

I'm not sure if I'm missing anything...
Thanks!
