REST - ERROR #6097: Error 'Read+28^%Net.HttpRequest.1' while using TCP/IP

REST - ERROR #6097: Error '<READ>Read+28^%Net.HttpRequest.1' while using TCP/IP device '9999'

Trying my first REST call operation to our internal EMR (Epic) server, and I am receiving "ERROR #6097: Error '<READ>Read+28^%Net.HttpRequest.1' while using TCP/IP device '9999'" when I attempt to test my operation. When I look up the General Error Messages for 6097 I am seeing...Error '%1' while using TCP/IP device $zu(189,1)='%2'. What does this mean?

I am trying to connect to the server over port 443 which is HTTPS but I am not using an SSL Configuration. Could that be the issue?

Is there a way to debug HTTP like their is with the ISCSOAP log?

Yes. Needs to use an SSL Configuration for HTTPS. Otherwise connection will close as handshake fails.

I tend to isolate to test a connection from server context if possible:

set request=##class(%Net.HttpRequest).%New()
set request.Server="www.intersystems.com"
set request.Port=443
set request.SSLConfiguration="TEST"
set request.Https=1
set tSC=request.Get("/",2)
do $SYSTEM.Status.DisplayError(tSC)

Switching the SSL off causes the error:

set request.Https=0
set tSC=request.Get("/",2)
do $SYSTEM.Status.DisplayError(tSC)
