Sending file attachments

[swt2c]

Is sending file attachments supposed to work, and if so, how?

I've tried using something like this:

    mai = MessageActivityInput().add_attachments(
        Attachment(
            content_type=content_type,
            content_url=content_url,
            name="Attachment Name",
        )
    )
    await ctx.send(mai)

But all I get in response is a box with the attachment name that I can't click or download.

Hi @swt2c, do you mind providing the values of your content_type and content_url?

[swt2c]

I tried all kinds of things but for content_type I was trying application/vnd.openxmlformats-officedocument.wordprocessingml.document and for content_url I was using a link to a public asset on AWS S3.

@swt2c I just noticed that you're using DevTools, right now we only support adaptive cards as attachments. It should render correctly if you test on Microsoft Teams directly. In addition, make sure you have the supportFiles param toggled to true in your manifest.json
