Hi,

it would appear this extension does not respect some API caveats, specifically the allowed length of the message body.

Long messages should be shortened or split.

Also notice the different responses from Discord, "Must be 4000 or fewer in length" and "Must be 2000 or fewer in length".

Using DLL v2.0.2

Message handling has been left to plugins to handle if they need to be split as the extension wouldn't know where to split the message at. In the next version, messages will perform validation before submitting and throw an error if they're creating an invalid message request.
