Looks like after the latest update discord webhooks no longer work with enchanced ban system
example of a test ban (using enhanced ban system):
Failed to call hook 'API_SendFancyMessage' on plugin 'DiscordMessages v2.1.3' (JsonSerializationException: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Oxide.Plugins.DiscordMessages+EmbedBuilder' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
