Retrieve Salesforce Attachement

[Polymer3]

First time using the forums

I am trying to use http to get a file from Salesforce and attach it to a SharePoint list.

I am running into an issue where it seems that the file is stored in base64 and cannot be decoded.

As far as I can see the rest of the flow works fine, it successfully authenticates but seems to have a problem retrieving the image.

HTTP get requestError
