Or can I change namespaces within one connection object?

Working on wrapping an IRIS Cache ObjectScript method that runs for a few seconds. Trying to get UI updates to show BEFORE the method runs in an async/await function. But it seems to be running synchronously rather than asynchronously . So my question is does IRIS/ObjectScript CSP pages support futures with JavaScript or does it run all synchronously.

I am trying to catch an exception and write it to the Application Error Log, but cant find any details on how to do this in IRIS health.

        Catch ex {
            Set logger = ##class(%Logger).%GetLogger("MyApp")
            Do logger.Error($ZError)
        }

Cant seem to find the %Logger class either.

I am trying to create users who only have `%SQL` Role for the INSTANCE. But I am unable to find any documentation on the ` Security.Users` class.

See:

    // Instantiate the Security.Users object
    Set userObj = ##class(Security.Users).%New()    
    // Set the username and password
    Set userObj.Name = userName
    Set userObj.FullName = userFullName
    Set userObj.Namespace = "USER"
    Set userObj.Roles = "%SQL"
    Set sc = userObj.ChangePassword(passwd)    
    // Save the user to the database
    Set ss = userObj.

I am doing a form POST to myself (same class) and when I do the form action it gets a page similar to the error page but just says:

Invalid action

There is nothing in the application error log. How can I troubleshoot this?

I recently started trying out Python in IRIS, but now I get this message repeated over and over again:

^Sources is not setup so hooks will not work

No idea where this came from and how it started. Any suggestions?

I am trying to get the value of a Submit button on a CSP object page.

<input type="Submit" value="Assign" name="action" id="action">

I tried getting it thru $GET(%Request.Data("action")), but it throws an Undefined error. Isnt $GET supposed to handle it if its undefined anyway?

How do I get the "value" of the button pushed when the form is set to POST?
