Hello, Could you please share how you solved it ? 
I am also facing same issue in save as attachment. I have specified header as "*/" and also as application or octet stream. Security also I have altered to download the required extension attachments. Also I have uploaded the attachment manually and verified, its uploading. But this automation step is failing with same error repeatedly.
