Unable to display error message with gs.addErrorMessage() or gs.addErrorMessage(gs.getMessage())

[Jiajie Li]

Hello experts,

I am trying to prevent duplicate software entitlements. If a duplicate is found, I want the request to abort and an error to show up. However, the error is not showing up. I tried both below:

gs.addErrorMessage(gs.getMessage('Duplicate software entitlement found'));//display error message

gs.addErrorMessage("Duplicate software entitlement found");//display error message

Below is the full business rule script:

(function executeRule(current, previous /*null when async*/) {

    // Check for existing entitlement with the same software and licensee

    var gr = new GlideRecord('alm_entitlement'); //create a new GlideRecord to query "alm_entitlement" table

    gr.addQuery('assigned_to', current.assigned_to); //query the assigned_to field

    gr.addQuery('licensed_by', current.licensed_by); //query the licensed_by field

    gr.query();

    if (gr.hasNext()) { //checks if there is at least one record in the result set of the GlideRecord query. 

    //If there is a matching record, the hasNext() returns true, and the code inside the if statement is run.

        gs.addErrorMessage(gs.getMessage('Duplicate software entitlement found'));//display error message

        gs.addErrorMessage("Duplicate software entitlement found");//display error message

        current.setAbortAction(true); //abort process

    }

})(current, previous);

The script works fine in my instance.

When are you running your BR?

[Jiajie Li]

I am running BR on Before Insert and Update

[Peter Bodelier]

That should be fine.

Is your BR triggered at all? If you add a gs.info('debug BR') line at the start of your script, do you see this is the system log? If not, please verify your conditions.

I added gs.info and it does run the BR

The following error does show up in the log:

Flow Designer: Operation(Deploy Workstation Request.If$9.1b44563b97c431502a7733471153afeb.624b63b5979c39502a7733471153af3e.f9e09916c31332002841b63b12d3aeaa) failed with error: com.snc.process_flow.exception.OpException: Error occured while inserting record: Operation against file 'alm_entitlement_user' was aborted by Business Rule 'Ensure no duplicate entitlements^dfee9e8a97fcbd102a7733471153af3b'. Business Rule Stack:Ensure no duplicate entitlements

I think this error is because of current.setAbortAction(true);

I also checked the conditions is empty. Is that the cause? I'm not sure what the condition should be.
