Please describe the problem you are having in as much detail as possible:
The .animated property is only sent across if it is actually animated. Right now, if it is not sent across, it will be undefined. This could default to false instead.

Under the hood, it looks like they call this utility method:

Include a reproducible code sample here, if possible:

<Client>.channels.resolve("channel_id").send({
  content: "content",
  components: [
    {
      type: "ACTION_ROW",
      components: [
        {
          type: "BUTTON",
          style: "PRIMARY",
          label: "label",
          customId: "customId",
          emoji: "non_animated_emoji",
          disabled: false
        }
      ]
    }
  ]
}).then(message => console.log(message.components[0].components[0]));

MessageButton {
  type: 'BUTTON',
  label: 'label',
  customId: 'customId',
  style: 'PRIMARY',
  emoji: { id: 'id', name: 'name', animated: undefined },
  url: null,
  disabled: false
}
