I would recommend using plain %CSP.REST and calling BP/BO from it. Here's how. You'll need to replace async call with a sync one to get response back, but the rest of the logic would be the same.

InterSystems IRIS natively supports WebSockets protocol as a client (your case) and as a server.

Consider upgrading.

Demo does not work rn

I would also recommend rewriting this property:

Property "cdsm_Physician_Issue_ID" As %String;

like this:

Property physicianIssueID As %String(%JSONFIELDNAME = "cdsm_Physician_Issue_ID");

This way JSON would still be imported, but you would be able to refer to property name without double quotes.

Get 0th array element from your array:

Class test.Provider Extends (%RegisteredObject, %JSON.Adaptor)
{

Property physicianFirstName As %String;

Property physicianLastName As %String;

Property physicianMiddleNameInitial As %String;

Property physicianSpecialty As %String;

Property physicianNPI As %String;

Property physicianMPIN As %String;

Property physicianTaxID As %String;

Property physicianADRId As %String;

Property physicianAddressLine1 As %String;

Property physicianCity As %String;

Property physicianState As %String;

Property physicianZip As %String;

Property physicianZipPlus4 As %String;

Property physicianPhone As %String;

Property facilityNPI As %String;

Property facilityAddressLine1 As %String;

Property facilityCity As %String;

Property facilityState As %String;

Property facilityZip As %String;

Property error As %String(MAXLEN = 200);

Property "cdsm_Physician_Issue_ID" As %String;

        "facilityState": "\"\"",
        "facilityZip": "\"\"",
        "error": "Invalid NPI. Requested NPI should contain 10 numeric digits",
        "cdsm_Physician_Issue_ID": "null"
    }
]
}

/// do ##class(test.Provider).Test()
ClassMethod Test()
{
    set json = ..GetJSON()
    
    set obj = ..%New()
    set sc = obj.%JSONImport(json.%Get(0))
    
    zw sc,obj
}

}

Interesting.

First of all I would recommend reading these two documents available on WRC (Software Distribution - Docs):

• InterSystems IRIS Adoption Guide
• InterSystems IRIS In Place Conversion Guide

First one explains the differences between Cache and InterSystems IRIS and the second one is about automated in-place conversion from Cache to InterSystems IRIS.

I would recommend the following steps:

• upgrade to 2016.2
  • This is the place to uplift your application - on the one hand it's still Cache so upgrade is simple, on the other the code, even with the new 2016.2 features would probably run fine on InterSystems IRIS
  • if you're using SQL - start using frozen plans
  • if you're using JSON - new JSON features become available here (dynamic objects)
• upgrade to 2018.1 (latest micro)
• perform in-place conversion to the latest InterSystems IRIS

Can you please provide an example?

And the error you're getting.

Check this topic.

If you encounter mismatch you should return immediately and not continue iterating.

Why do you want to kill all BH jobs directly?

You can just disable a BH and it would effectively do the same:

set sc = ##class(Ens.Director).EnableConfigItem(BH, 0)

I have ordered Raspberry Pi 4 a month ago, any news when would it ship?
