Cannot upload/encrypt and download/decrypt an attachment via REST through the Edge Encryption proxy.

1. Log in as administrator in a pre-Kingston instance.

2. Activate the Edge Encryption plugin.

3. Set up a proxy pointing to the instance.

4. On the Service Portal, open a session using the Edge Encryption proxy.

   Note that you can add attachments. Also, the generated [sys_attachment] records are not encrypted, and can be accessed in a session not using the Edge Encryption proxy.

5. Create an Incident record invoking a preprogrammed REST API (JS or C#NET) with a POST action and JSON format towards the Incident table.

   Note that the call is unsuccessful and throws a Gateway Timeout error. The REST API call with the GET action to the Incident table might be successful and return records.

The workaround on pre-Kingston instances is to use POST requests to sys_attachment.do for REST attachments.
