It might be that you are not passing an string trough but an object or array.

I have this same error. I'm using firebase with polymerfire. If i bind a firebase document to data then bind <marked-element id="el" markdown="[[data]]"> I'll get several of these errors.

I got around that by setting up this observer:

observers: [
  '_dataChanged(data, data.*)'
],

_dataChanged: function(data) {
  if (typeof data === "string") {
    this.$.el.markdown = data;
  }
}

That works fine but it would be nice if marked.js handled this check for me so i could just bind onto my data and go.
