Flow Email Attachment Content as varbinary(max) parameter to stored procedure

Hello,

Idea is Flow listens for emails and inserts attachments to a SQL Server FileStream filetable as such:

The stored proc executes with the following error: 

400 - Invalid binary encoding

This is the cleanest way for me to do the insert for each attachment but comes down what is the binary type sent? I

Hi @Bukester ,

FileSystem is not a datatype and is enabled as an attribute on a Varbinary (max) column.

Please use the conversion functions to convert the value’s type to see if it will work:

Base64ToBinrary

Best regards,

Mabel

Thanks Mabel! Do we agree that its the "Attachment Content" that is the file itself? The payload so-to-speak? It has to be. I'll try your suggestion and update the post. It would be great if it was. Otherwise, I'd have to copy to the directory presented by the FileTable, which is not so bad anyhow.

No luck. It still doesnt like the "Invalid binary encoding." I can also see that the stored procedure is never called, so Flow is not capable of constructing the RPC call at all. Its failing within flow.

This is saying its available in PowerApps but not in Flow. But thats as of August 2018.
