Virtual Agent topic visibility using vaContext.portal persists across portals in same session

[ashutoshkum]

Hello Community,

I have implemented portal-based topic visibility in ServiceNow Virtual Agent using vaContext.portal, but I’m facing an issue where the portal context is not refreshing correctly between portals.

My setup:

• I have two Service Portal portals (for example: sp and esc)

• Same Virtual Agent widget is used on both portals

• In Virtual Agent topic Properties → Condition, I’m using:
  
  

  (function execute() {

          if(vaContext.portal == 'esc'){

                  return true;

          }else{

                 return false;

          }

  
  

  })()

Expected behavior:

Topics should be visible only on their respective portals.

Actual behavior:

When I first open VA on portal sp, vaContext.portal is correctly set to sp and topics behave as expected.

But when I then open VA on portal esc (same user/session/browser):

vaContext.portal still holds value sp, and topics remain hidden on esc.

It seems the VA web client session/context is being reused and not refreshing the portal value per launch.

What I tried:

• Verified iframe URL contains correct sysparm_portal

• Logged vaContext using gs.info(JSON.stringify(vaContext))

• Topic condition logic is correct

But context still persists from first portal load.

My questions:

1. Is Virtual Agent context cached across portal launches in the same session?
2. Is there a supported way to refresh/reset VA context per portal?
3. Is using sysparm_reset=true or cache-buster parameters the right approach
4. Is there a better OOTB approach for portal-specific topic visibility?

Any guidance from those who have implemented multi-portal VA setups would be appreciated.

Thank you!
