Uploading files via webhook only shows embed payload

[elmoiv]

Files uploaded via webhook with embedded payload suddenly stopped showing the file in the message for no apparent reason.

• Uploaded file type: .7z
• The code used:

from discord_webhook import DiscordWebhook

def upload_file(fpath):  
    embeds = [
            {
                "fields": [
                    {
                        "name": "RGAC File Upload",
                        "value": 'TEST'
                    }
                ],
                "color": 0xeaddca,
                "title": "RGAC Session File",
                "image": {
                    "url": "attachment://{}".format(os.path.basename(fpath))
                },
                "footer": {
                        "text": "Captured by RGAC system"
                    },
                "thumbnail": {
                        "url": THUMB,
                    }
            }
        ]

    webhook = WEBHOOK

    wh = DiscordWebhook(
            url=webhook,
            embeds=embeds,
        )

        
    with open(fpath, "rb") as f:
        wh.add_file(file=f.read(), filename=os.path.basename(fpath))

    try:
        wh.execute()
    except:
        err = traceback.format_exc()
        print(err)
        return 1

    return 0
