 getUserInfo: function(){
        var usr = this.getParameter('sysparm_user');
        var gr = new GlideRecord('sys_user');
        if(gr.get(usr)){
            return gr.manager;//make change here
        }
          
    },

@Bharath39 Not sure if there are any junk characters in your client script, I got the javascript errors when I copied the client script and script include. I have made the below changes and it is working, please check

Script Include:

var GroupManager = Class.create();
GroupManager.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getUserInfo: function() {
        var usr = this.getParameter('sysparm_user');
        var gr = new GlideRecord('sys_user');
		if (gr.get(usr)) {
            return gr.manager;
        }
		return '';

    },
    type: 'GroupManager'
});

Client Script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
     var ga = new GlideAjax('GroupManager');

    ga.addParam('sysparm_name', 'getUserInfo');
    ga.addParam('sysparm_user', newValue);
    ga.getXMLAnswer(function(answer) {

        //alert('XML-Answer-'+answer.split(','));
        alert(answer);
		g_form.setValue('requester_manager',answer);
    });

}

Please mark the appropriate response as correct answer and helpful.

Thanks!!
