Usually response does contain status information in StatusCode and StatusLine properties.

You need to change this line

Set httpResponse = httpRequest.Post("/sample/", 2)

to

#dim sc As %Status = $$$OK
Set sc = httpRequest.Post("/sample/", 2)
Write $System.Status.GetErrorText(sc)

As Post method returns status.

After debugging you can use

write $$$ISERR(sc)

macro to check if result of some operation is an error.

Check your current server locale.

it causes error messages as something in the class is not correct,

What error messages?

Also try calling

zwrite %objlasterror

it may contain additional information.

You can use methods of %Activate.TLEnumerator class to load libraries programmatically.

Redefine HTTP adapter like this:

Class Production.Adapter.HTTPOutboundAdapter Extends EnsLib.HTTP.OutboundAdapter
{

/// Send a POST to the configured Server, Port and URL, sending form data to the named form variables.
Method Post(Output pHttpResponse As %Net.HttpResponse, pFormVarNames As %String, pData...) As %Status
{

    quit ..SendFormDataArray(.pHttpResponse, "POST", ..GetRequest(), .pFormVarNames, .pData)
}

ClassMethod GetRequest() As %Net.HttpRequest
{
    set request = ##class(%Net.HttpRequest).%New()
    set request.ContentType = "application/json"
    quit request
}

}

And use it instead of default adapter.

Try this:

1. Write stream to string

2. Use $zcvt on string $zcvt(string,"O","UTF8")

3. Send this stream to XSLT

Cache private web server is configured and available by default.

If System Management Portal opens then private server works.

Here's a good tutorial on developing Angular applications on Caché.

Please check the output:

set result = ##Class(%File).Delete(fileNamewithPath, .status)
zw result
zw status

There are several ways to do that. Let's say you have a persistent property

Property Problem As %String;

That you don't want anyone to see.

1. Make it private:

Property Problem As %String [ Private ];

It would not be displayed altogether

2. Add accessor methods:

Property Problem As %String;

Method ProblemGet() As %String [ ServerOnly = 1 ]
{
    Quit "****"
}

Method ProblemRealGet()
{
    Quit i%Problem2
}

Method ProblemSet(Arg As %String) As %Status [ ServerOnly = 1 ]
{
    Set i%Problem2 = Arg
    Quit $$$OK
}

This way default callers would get **** and only your app code can access the real value.

3. Do not project property to XML

Property Problem As %String(XMLPROJECTION = "none");

As ensemble message viewer is XML-based it would hide property from it.

4. Create a special datatype. For example MyApp.Datatype.Password datatype returns **** as Display and ODBC values:

Class MyApp.Datatype.Password Extends %String
{

ClassMethod LogicalToDisplay(%val As %String) As %String [ Internal ]
{
    q $case(%val,"":"",:"*****")
}

ClassMethod LogicalToOdbc(%val As %String) As %String [ Internal ]
{
    q $case(%val,"":"",:"*****")
}

}

To use it:

Property Problem As MyApp.Datatypes.Password;

5. Extract the property into a separate class and reference the object of that class.

These approaches could be combined.
