What happened?
ListTaskPushNotificationConfigResponse directly returns a ListList<TaskPushNotificationConfig> as its result
but that's not the payload defined by the spec:
// Represents a successful response for the `tasks/pushNotificationConfig/list`
// method.
message ListTaskPushNotificationConfigResponse {
// The list of push notification configurations.
repeated TaskPushNotificationConfig configs = 1;
// A token, which can be sent as `page_token` to retrieve the next page.
// If this field is omitted, there are no subsequent pages.
string next_page_token = 2;
}
The list of configs must be wrapped in a config fields and the nextPageToken field is missing.
