I am trying to capture User Action using addAction, addActionProperty, leaveAction, however the addActionProperty does not work, though I created Javascript Variable for the properties i am passing in addActionProperty.

How did I create;  
Click on Application \> Edit \> Capturing \> Session and action Properties \> Add Property \> Custom defined property.

And then I chose Javascript Variable put other details.

My code below;  
const dtrum = window?.dtrum;  
if (!dtrum) {  
logger.info(`trackCustomUserAction (dtrum API undefined) actionName=[${actionName}] `);  
return;  
}

const actionId = dtrum.enterAction('feature\_initialized’);

if (properties && typeof dtrum.addActionProperties === ‘function’) {  
dtrum.addActionProperties(actionId, null, null, {status, action});  
}

dtrum.leaveAction(actionId);

So when my code is executed the values does not seems to be logged in dynatrace.

However, if i set property values in global windows then Dynatrace UI grabs the value and logs the status and action for the user. Below ithe working code

const actionId = dtrum.enterAction('feature\_initialized’);

//Created Javascript variable in Session and User Property  
// capture expression named as DT\_OBSERVABILITY  
// assigning it in global window, so that dynatrace UI could capture value  
window.POC = window.POC || {};  
window.POCstatus = values?.status ?? ‘’;  
window.POC.action = values?.action ?? ‘’;  
dtrum.leaveAction(actionId);

I am trying to understand why addActionProperty does not work, is it related to Our Dynatrace tenant runs on RUM Classic Gen2 without DPS licensing. I see that we do not have experience vital and user events available. Could someone help clarify as I need to document this as I am trying to log user actions in our web application

The issue is here:

> And then I chose Javascript Variable put other details.

Choosing “Javascript **variable** ” will lead to the behaviour you mentioned here:

> However, if i set property values in global windows then Dynatrace UI grabs the value and logs the status and action for the user.

What you want is to select “JavaScript **API** ” instead.
