I have added a new version  for the GLOBALS contest
To take care of large Globals that may break your available memory.
The JSON Object is exported to a file. and there is also the related loader

New Version 0.1.0

USER>write ##class(dc.GblToJSON.EX).export("^dc.MultiD")
File gbl.json created

And the related loader creates the Global

USER>write ##class(dc.GblToJSON.EX).import()
Global ^dc.MultiD loaded

It is of course also available in the Online Demo facility.  
And to see the generated file there is a show() method

USER>write ##class(dc.GblToJSON.EX).show()
{"gbl":[
{"node":"^dc.MultiD","val":5},
{"node":"^dc.MultiD(1)","val":"$lb(\"Braam,Ted Q.\",51353)"},
{"node":"^dc.MultiD(1,\"mJSON\")","val":"{}"},
{"node":"^dc.MultiD(2)","val":"$lb(\"Klingman,Uma C.\",62459)"},
{"node":"^dc.MultiD(2,2,\"Multi\",\"a\")","val":1},
{"node":"^dc.MultiD(2,2,\"Multi\",\"rob\",1)","val":"rcc"},
{"node":"^dc.MultiD(2,2,\"Multi\",\"rob\",2)","val":2222},

Hi @Joel Solon ,  I see it that way:
COS  is aged but was not as short as M (even more aged)
but InterSystemsObjectScript  are 24 Character to type ! 
At least 18+ chances for mistyping with my old fingers. laugh
So I have my personal FLA  (4 letter abbreviation)  to write  "new-speak" and get it sorted right.

LOAD DATA was released with IRIS 2021.2 and was unknown before
Your version is 2020.1  only.
Sorry

If your global is part of a class/table class parameter DSTIME could be an approach.
or any SQL trigger or any %OnAfterSave,  %OnAfterDelete, ...
 
For pure Globals all you have is the Journal (if enabled)

You may try an external RTF parser to run your conversion  using CPIPE or $ZF(-100-)
and then consume the result. 
1 Example of many others in Google:  striprtf (py) 
Once you move to a version supporting Embedded Python you can run it even internal

OK. after some detailed analysis I found these facts that I forward to WRC:

  • normal JOB command ISOS/COS
    • returns $TEST to signal success/fail
    • $ZC the id of the started job.
    • this happens after complete init of the job or eventually timed
    • is always ASYNCHRONOUS  to the background job
  • JOB command for Embedded Python if not timed
    • Hangs until AFTER completion of the started job
    • then return $TEST and $ZC which is useless as the job is gone!
    • acts SYNCHONOUS to the started job 
  • timed JOB command for Embedded Python
    • returns after the timeout with $TEST = 0  ==> FAILED
    • does not return the id of the started JOB
    • though the started Job may work fine
    • you just don't get info and may find out by other means if it is OK
  • Workaround until a fix.
    • Start a background job as ISOS/COS Class Method
    • let this class method start your method in Embedded Python.

Another reason why Embedded Python Pure is just a fiction

Hi @Scott.Roth. I'm sure you have access to WRC
under Previews there is a standalone kit Studio-2022.1.0.131.0-win.msi
and it is backward compatible as usual.

Hi @Stuart Strickland !

This well-known effect is named Proleptic Gregorian Calendar.
A bunch of other DBs is using it as well. As well as my favorite competitor O*****.
This means it calculates backward as if we always had the Gregorian date since the beginning
and the lost days in  October 1582 and other adjustments are ignored.
In fact, at that time almost every country and smaller had its own calendar. Often like "in the 3rd month of the 7th year of the reign of Duke Goofy 4th".  And converting regional dates from Spain to England or Franc or Italy or Ireland or even Scandinavia is a special mathematical exercise for students of History. On top of that, you often don't have the information if they counted years by Sun calendar or by Moon calendar.

you should check a few things upfront
- is your Caché a 64 bits installation and is the   pythonbind3.c  also compiled for 64 bit   (or both 32bit)
  this might be one possible reason for the "data mismatch" you mention
- pythonbind3.c seems to be a C code using the Callin Interface.
  this requires Service %Service_CallIn to be enabled with user, passwd, ...
- next check the SuperServer Port (default = 1972)
- connect to a USER namespace. Since %SYS requires rather high privileges.
- then check if the connection really works.
  once established it should be possible to identify the related process from
  System Management Portal / Operations / Processes showing the client_exe, namespace, ...
- then you may start composing queries.

it is in Namespace %SYS
Class %CSP.UI.Portal.EnsembleMonitor

if you use a class name starting with %Z* you can even have it in %SYS

A little bit of guessing from my side. behind your page /csp/test/person.csp
there is a namespace  (eg. USER)  with DB user 
If you have no login page you run as "UnknownUser" 
If it has no access rights or appropriate roles (most likely) for this DB behind you are lost;

2 possible workarounds: 

  1. give "UnknownUser"  enough rights for this Namespace and/or DB. 
    • but this is then valid not just to this specific CSP page
    • not really recommendable
  2. create a new user with the required rights
    • on your CSP page you can assign this user undercover by method
    • %CSP.Session.Login() and you have PW under control
    • no need  to touch "UnknownUser"

Robert Cemper · Feb 28, 2022 go to post

with CSP you have a license user that can be changed by %CSP.Session.Login()

Login with this username and password, returns a status code to show if it worked or not. This method also trades license units at the same time so this CSP session will be logged in as a named user. If you pass type=1 then this will trade licenses only and not login as this user. After the login completes it also updates the property Username to match the $username value this session is logged in as. The property LicenseId is also updated to be the license identifier that this session is logged in with.
If a login fails then the property Username and property LicenseId will remain at their previous values. If you pass oldpassword then this will attempt to change the password of username from oldpassword to password and login as this user. Note new status return values: CSP applications can be two-factor-enabled. If the current application is one such, then if Login() successfully authenticates the username/password, it does not return $$$OK, but rather $$$CSPPendingTwoFactorAuthentication. During Two-Factor Authentication, an 8-character numeric security string will be sent to the user's cellphone. You must obtain this string from the user and call CompleteTwoFactorLogin^%CSP.Session() to complete authentication of this user. Also note that if the login SUCCEEDS (status returned will be $$$OK), but you were unable to secure a license, the new apperr parameter will have the value of $$$CSPErrorTradeLicense. In such a case, you may have to call the Login function again to trade a license. If you are calling merely to trade a license (type=1), then if the license trade fails, Login will return a status of $$$CSPErrorTradeLicense.

Version is not the reason. It is %JSON Adaptor that breaks it. 
Removing it let it compile.  Just tried it with 2022.1 preview
I suggest you deposit a bug report at WRC. Either compiler od Doc is wrong

You reference the documentation  for 

but your $ZV shows.

$ZV: IRIS for Windows (x86-64) 2021.1 (Build 215U) Wed Jun 9 2021 09:39:22 EDT [Health:3.3.0]
this might be the reason !

The difference is significant.

detailed description is here  Defining an XData Mapping Block

  XData {MappingName}
  {
    <Mapping  {ClassAttribute}="value" [...] xmlns="http://www.intersystems.com/jsonmapping".>
      <{Property Name}="PropertyName" {PropertyAttribute}="value" [...] />
      [... more Property elements]
    </Mapping>
  }

Just checked.  The method  uses  %XML.Reader=##class(%XML.Reader).%New()
So you better  compose a nice XML description.
this tells you what is expected:

Do reader.CorrelateRoot("%JSON.Mapping")

And that's the description
classmethod GenerateMappingFromXdata(class As %String, ByRef mapping) as %Status

Get the JSON adaptor configuration information from class and property parameters.

BUT:
https://docs.intersystems.com/iris20212/csp/documatic/%25CSP.Documatic.cls?&LIBRARY=%25SYS&CLASSNAME=%25JSON.Generator

This class is used internally by InterSystems IRIS. You should not make direct use of it within your applications. There is no guarantee made about either the behavior or future operation of this class.

It looks like your JSON Mapping is already content of what you labeled XDATA.
The essence of XDATA is to contain an XML structure to describe your data.
that is to be transformed into a JSON mapping. 
In your case, you have the mapping already in hands.
So what other mapping would you expect ? 

Robert Cemper · Feb 25, 2022 go to post

No, I have no solution.
As all development on Caché (except serious bugfix) is frozen I wouldn't expect this to come.
You may migrate your Caché to IRIS. Or use some other way (REST ?) for access.

my personal experience dates back to ~2007 or so.
converting tables using SQLGatewy at the customer side was rather simple.
rewriting ALL stored procedures (in COS) was an enormous effort.
Finally, the soultion provider located in NYC refused cooperation.
This was an O* Platinum Partner.
ISC sales in NYC couldn't convince them crying
