I am experiencing an intermittent issue when attempting to upload attachments. Sometimes the upload succeeds, while at other times it fails with the following error message

{ "error": { "message": "(#100) Upload attachment failure.", "type": "OAuthException", "code": 100, "error_subcode": 2018047, "fbtrace_id": "AVRUCyBKS8bJTYPcC7DFJ6R" } }

The attachment in question is the same image file. I have confirmed that the file size and format meet the upload requirements. Could you please provide some insights into what might be causing this issue and how it can be resolved?
