This is a great resource, nice work and a top chapter in this series for sure.

There seems to be different ways to approach declared IRIS state by codifying things, you can codify the exported objects and import them or like you mentioned, use the installer method that builds things as code.... which I have had pretty good success with in the past, like Tasks below.

<Method name="CreateClaims">
<ClassMethod>1</ClassMethod>
<FormalSpec>pVars,pLogLevel,tInstaller</FormalSpec>
<ReturnType>%Status</ReturnType>
<Implementation><![CDATA[


Set configItems = $LISTBUILD(

$LISTBUILD(1,
"Return payload from customer",
"create 835 from adjudicated claims",
"NS.Package.Task.CreateClaim")


for i = 1:1:$LISTLENGTH(configItems) {

    Set item = $LISTGET(configItems, i)
    Set Task=##Class(%SYS.Task).%OpenId($LISTGET(item,1))

    if 'Task {

        Set Task = ##Class(%SYS.Task).%New()
        Set Task.Name = $LISTGET(item,2)
        Set Task.Description = $LISTGET(item,3)
        Set Task.NameSpace = "USER"
        Set Task.Type = 2
        Set Task.TaskClass= $LISTGET(item,4)
        Set Task.TimePeriod = 5
        Do Task.idSet($LISTGET(item,1))
        Set Task.RunAsUser = "intersystems"
        Set status=Task.%Save()
        $$$ThrowOnError(status)

    }

}

]]></Implementation>
</Method>

In the FHIR Accelerator you can head to "Data Management -> Bundle Operations" and find sample scenarios in there.  At the end of the day theses are bundles generated by Synthea so you can upload populations you create from that tool directly in for your use.  If you want some help generating a specific population give us a hint and can help with that during that hack.

 

Follow up here,  apache conf needed a directive for the move forward.

The previous Gateway/IRIS combination did not require the below apache directive, but the upgraded setup certainly required.

<Location />
CSP On
</Location>

Docs do not really show it called out directly to turn on this apache directive for the root at all in the documentation but that is what was done to make it compatible in the declared version combination in case you run into this combo on similar configurations.

Thanks to Connie at the WRC for taking an in-depth look in short order.
