Attachment interface has contentType property but only content_type works

[miguelnv]

When trying to send attachments while sending email, only content_type works and not contentType as Interface Attachment says it should be.

Version affected: https://github.com/resend/resend-node/releases/tag/v4.1.1

Hello,
I just found a workaround until they fix it :

export interface FixAttachment extends Attachment {
  content_type?: string,
};

await resend.emails.send({
  from: "",
  to: "",
  subject: "",
  attachments: [
    {
      filename: "",
      content: "",
      content_type: "",
    } as FixAttachment,
  ],
  text: "",
});

Seems like this was fixed in resend@4.8.0 in #554
