Calling Script Include from Client Script error - "There is a JavaScript error in your browser"

[mamason]

Not sure what the issue is.  I am able to call the script include from the window Scripts - Background and works as expected so I am assuming the issue is with how I am calling from client script.  I do have the script include Client Callable box checked.

Client Script

function onChange(control, oldValue, newValue, isLoading) {

   if (isLoading || newValue == '') {

      return;

   }

        varUser = g_form.getValue('add_user_to_group');

        varaddedUser = varUser.split(',').pop();

            var ga = new GlideAjax('CheckUserLicense');

            ga.addParam('sysparm_name', 'getUserLicense');

            ga.addParam('userId',varaddedUser);

            callTask.getXML(licenseResult);

            function licenseResult(response) {

            var userLic = response.responseXML.documentElement.getAttribute('answer');

            alert(userLic);

        }

}

SCRIPT INCLUDE

var CheckUserLicense = Class.create();

CheckUserLicense.prototype = Object.extendsObject(AbstractAjaxProcessor,{

    initialize: function() {

    },

    getUserLicense: function(userId){

        //var userId = this.getParameter('userId');

        var result = '';

        var grUser = new GlideRecord("sys_user_has_role");

        grUser.addEncodedQuery('user.sys_id=' + userId + '^role.nameLIKEitil');

        grUser.query();

        if(grUser.next()){

            result =  "license";

        }

        else

        {

            result = "noLicense";

        }

        return result;

    },

    type: 'CheckUserLicense'

});

CALLING SCRIPT INCLUDE FROM SCRIPTS - BACKGROUND

var CheckUserLicense = new CheckUserLicense();

var result = CheckUserLicense.getUserLicense('6cccca19f4ead980776706f2f4caa3c6');

gs.print(result);

Depending on the user it will return string of license or noLicense but when calling from client script on the change of the variable I get "There is a JavaScript error in your browser"

Any Help would be greatly appreciated!

"callTask" should be "ga"

In addition to "ga" instead of "callTask" in the Client Script, the Script Include should not have the initialize function, which may not matter, but you do need the commented out getParameter line in place of the function argument.  Here's an excellent guide to review what is needed, and covers how to return more than one value.

@mamason Update your scripts as follows.

Client Script:

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
        varUser = g_form.getValue('add_user_to_group');
        varaddedUser = varUser.split(',').pop();

            var ga = new GlideAjax('CheckUserLicense');
            ga.addParam('sysparm_name', 'getUserLicense');
            ga.addParam('userId',varaddedUser);
            ga.getXML(licenseResult);

            function licenseResult(response) {
            var userLic = response.responseXML.documentElement.getAttribute('answer');
            alert(userLic);
        }
           
}

Script Include:

var CheckUserLicense = Class.create();
CheckUserLicense.prototype = Object.extendsObject(AbstractAjaxProcessor,{
    initialize: function() {
    },

    getUserLicense: function(userId){
        var userId = this.getParameter('userId')?this.getParameter('userId'):userId;
        var result = '';
        var grUser = new GlideRecord("sys_user_has_role");
        grUser.addEncodedQuery('user.sys_id=' + userId + '^role.nameLIKEitil');
        grUser.query();
        if(grUser.next()){
            result =  "license";
        }
        else
        {
            result = "noLicense";
        }
        return result;
    },

    type: 'CheckUserLicense'
});

Hope this helps.
