Event Forwarding - Error "Referenced Data Element are not added to the build: arc.event.xdm"

[jlasso71]

Hi there,

I am trying to use Event Forwarding to send data to other systems dynamically. The scenario is multi-brand, so I have different XDM schema fields referring to the same concept (e.g.: identities.brand1.ecid, identities.brand2.ecid). I want Event Forwarding to adapt the request depending on the origin (brand) of the data, so I have decided to create a dynamic Data Element via custom JS code:

let ecid;
var xdmObject = getDataElementValue('arc.event.xdm');

if(xdmObject){
    if (url.includes("brand1.com")) {
      ecid = xdmObject._sandboxname.identities.brand1.profile.ecid.id;
  } else if (url.includes("brand2.com")) {
      ecid = xdmObject._sandboxname.identities.brand2.profile.ecid.id;
  } else {
      // Handle cases where the URL does not match any known hosts
      console.warn('Unknown host in URL:', url);
      ecid = "";
  }
}

return ecid

Nevertheless, when I try to Build the code I get the next error:

There was an error minifying your custom code.

Referenced DataElements are not added to the build: arc.event.xdm

Where am I doing wrong? I was assuming "arc.event.xdm" could be directly accessed from Event Forwarding custom code. Could you please provide some guidance on this?

Thanks in advance
