As always there is a possibility to get <INVALID OREF> while direct access of objects. So, we can use responseData.items.%Get(0).titles.%Get(0).value.%Get("en_US") with some additional checks like below.

If $IsObject(responseData.items) && (responseData.items.%Size()) {
    dao1 =responseData.items.%Get(0) 
    If $IsObject(dao1.titles) {
        dao1.titles.%Get(0).value.%Get("en_US")
    }
}

Hello @Jonathan Perry

The rules for routine name /Class name is "If you start a routine name with %, use z or Z as the next character after that" So, You have to create routine in the name of %zTest/%ZTest

We can use the %SYS.LockQuery class and its List query function to check whether the global is already locked. If it is, we can skip attempting to acquire the lock.

Check for the specific process

ClassMethod LOCK(Lock, Mode)
{
    If '..IsLocked("^A","X") {
        Lock +^A
    }
    Else {
        Write "Locked"
    }
}
// X - Exclusive
// S - Shared
ClassMethod IsLocked(Global As %String, Mode As %String)
{
    #dim status = 0
    Set tResult = ##class(%SYS.LockQuery).ListFunc($J)
    While tResult.%Next() {
        If tResult.Mode=Mode&&(tResult.LockString=Global) Set status= 1
    }
    Return status
}

However, the above code only checks for a specific process and does not account for other processes with Xclusive or Shared locks. The sample below checks for all acquired locks, returning their status and lock type.

ClassMethod IsLocked(Global As %String, Mode As %String)
{
	#dim status = 0
	Set tResult = ##class(%SYS.LockQuery).ListFunc()
	While tResult.%Next() {
		If tResult.LockString=Global {
			If tResult.Mode?1(1"X",1"S") Set status= 1_","_tResult.Mode
		}
	}
	Return status #; status be like "1,S" or "1,X"
}

Hello @Scott Roth 
You can see the http request format by using "The %Net.HttpRequest Send() method has a test argument as its 3rd option; setting it to 1 outputs the request, 2 the response, and 3 the response headers." Can you check this from the post. 

Thank you for sharing this @Keren Skubach

The SDA to FHIR / FHIR to SDA DTL(which is the primary method we're using for conversion) doesn't support primitive Extension conversion by default. I'll need to implement a custom DTL to achieve this. Alternatively, I can handle it in the code if I generate the FHIR resource programmatically. Can you attach the documentation link for the set resource.property = $listbuild(""original property value",<primitive extension index>,...) primitive extension index set as well. I could see the HS.FHIRModel.R4.Patient from 2024.1 version

Thank you!

When you extend a class with %JSON.Adaptor, you must also ensure that any child classes or classes used as object properties also extend %JSON.Adaptor. Otherwise, you'll encounter an error like:
" ERROR #9411: A class referenced by a %JSONENABLED class must be a subclass of %JSON.Adaptor" during JSON export.

In your case, %DynamicObject/%DynamicArray is a system class that does not extend %JSON.Adaptor, which is why you're unable to export it using methods like %JSONExport, %JSONExportString, or %JSONExportToStream.

To work around this, you can use the Property xAxis As %Library.DynamicObject(%JSONINCLUDE="NONE"); parameter on the problematic field to exclude it from the JSON export.

$ZDateH is used to convert the actual date into IRIS internal Horolog format. You can use $ZDate convert the Horolog to date format. The start date is $ZDate(0) = "12/31/1840" $ZDH("12/31/1840") = 0. If the date is earlier than the allowed range, it throws a 'VALUE OUT OF RANGE' error.

That's correct. I’ve explored the new UI feature, and it appears to be a commendable initiative. The following observations have been noted.

• The shortcuts for Rules, DTL, and Production at the top of the page, along with their options (Partial/Full/Open in New Tab), greatly improve navigation and allow for quick access within a single page.
• The file paths (File Path, Archive Path, and Work Path) within the File Service configuration are not selectable, and the target configuration name is not rendered correctly.
• The absence of the target configuration results in improper rendering of the connection arrows.
• In the new user interface, the Production Settings—specifically Queues, Logs, Messages, and Jobs—are not displaying any data, and the Action tab is missing. These elements function as expected in the standard interface.
• While small Data Transformation Layers (DTLs) and mappings display correctly, larger DTLs and mappings exhibit instability and are not consistently reliable in production configuration Singe page application.
• The popup displayed during the start or stop of a business host or production instance is helpful for identifying errors; and the 'Update' button is absent.
• And The dots appear feels somewhat unusual.

It takes some time to adapt to the new UI; however, it is quite effective and well-designed.

Thanks! 

Hello @Evgeny Shvarov 
I directly use %DymaicObject and %DynamicArray and its methods depends on the response type (array or object) to set the values into the JSON response and I use %WriteResponse to write that response to the API call

 Class sample.Impl Extends  %REST.Impl {
 
 ClassMethod GetAllPersons() As %Stream.Object
{
    d ..%SetContentType("application/json")
    set res =  {"name":"test" 
    do ..%SetStatusCode(200)
    do ..%WriteResponse(res)
    q 1
    
}

Mixed of stream data types and other datas then creates a stream and convert into DynamicObject if required and write that response.
