Meteor papaParse server side method call giving error


#1
Meteor.methods({
    'parseFile'() {
        Papa.parse('/private/file/buildingData.csv', {
            download: true,
            complete: function(results) {
                console.log("hi there how are you")
                console.log(results);        // array of rows
                return results;
            }
        });
    }
})

I have defined above methos in a seprate builidingData.js file in a folder named Methods. And I am calling this method from client under map.onRendered() using following code.

Meteor.call('parseFile', (err, res) => {
                if (err) {
                    alert(err);
                } else {
                    // success!
                }
            });

I did meteor meteor add harrison:papa-parse hence i don’t have to use script tag to include papaparse.js in html code.

Based on below comments now I am able to print data on server side but with following error:
