"Object [object Object] has no method 'replace'" on challenge of stage 3 of Creating a Basic Template Engine in Node.js

I'm getting a pretty basic JS error on this challenge (which basically indicates how to create a merge utility), "Object [object Object] has no method 'replace'".

I'm sure it is a super stupid mistake, but I can't seem to find where I went off.

Thanks!

index.js 
var utilities = require("./utilities");

var mailValues = {};

mailValues.first_name = "Janet";

var emailTemplate = "Hi %first_name%! Thanks for completing this code challenge :)";

var mergedContent = utilities.merge(emailTemplate, mailValues);

//mergedContent === "Hi Janet! Thanks for completing this code challenge :)";
utilities.js 
function merge(values, content) {
  for(var key in values) {
    content = content.replace("%" + key + "%", values[key]);
  }
  return content;
}


module.exports.merge = merge;

The challenge seems to have a problem with you switching the order of the parameters passed into the merge function. 

function merge(content, values)

Hi Nicolás,

Did you manage to find a fix for this?

@Julian's suggestion didn't work for me.

Thanks!
