Hello! I've tried to create a receiver in rancher for my alertmanager. In my receiver I need an oauth2 configuration. But if I add the oauth2 configuration my alertmanager won't load the receiver and there're no error messages in the logs. On my local system (without rancher) my alertmanager loads the receiver without problems. Is there something I do wrong? This is the receiver configuration which I created in rancher:

- name: 'Name'
  webhook_configs:
    - url: 'url'
      http_config:
        oauth2:
          client_id: 'id'
          endpoint_params:
            grant_type: 'string'
          client_secret: 'secret'
          scopes:
            - 'string'
          token_url: 'url'
