embeds field in messages endpoint can be null on discord but not spacebar

[gizmogoat]

Describe the bug
When sending messages, the field "embeds" is allowed to be null on Discord's real API, but not on Spacebar's.

To Reproduce
Steps to reproduce the behavior:

1. Send an HTTP request to the channels/id/messages endpoint through a bot with a null embeds field.

Expected behavior
Spacebar API is unbothered by "embeds": null like real API

Console Logs
[0006] ERROR gateway: SendMessage failed: HTTP 400 Bad Request, {"code":50035,"message":"Invalid Form Body","errors":{"embeds":{"_errors":[{"message":"must be array","code":"type"}]}},"_ajvErrors":[{"instancePath":"/embeds","schemaPath":"#/properties/embeds/type","keyword":"type","params":{"type":"array"},"message":"must be array"}],"request":"POST /api/v9/channels/1475017016980037677/messages"}

The two requests above are sent via Matterbridge and a simple mitmproxy script to reroute to different destinations based on the token length. They both have the same request body.

Can you test again with commit 1926e8c or newer?

That seems to work when sending as a regular user. But this problem is also true of the "components" field on the webhooks endpoint. Matterbridge sends it as null too, and that, too, breaks with Spacebar. Is that different enough that it should have a separate issue?

What error are you getting with that now? From what I can tell components should be nullable

I am attempting to recreate this on my branch and using the following payload

{
  "type":0,
  "content":"[spacebar] whinis something",
  "attachments": [],
  "embeds": null,
  "embed": null,
  "flags": 0,
  "components": null,
  "channel_id": "{id}"
}

And hitting
POST /api/v9/channels/{channelid}/messages

I am getting no issues.

I do notice that's at the channels endpoint -- when I mentioned above, I was hitting this problem on the webhook endpoint. It should be fixed for the regular message send endpoint now. Part of my question was if this was different enough that it should be a separate issue or is fine to stay here.
