Polymer2- Iron Ajax not working

Nagasai-Aytha commented 7 years ago

I am trying to bind local properties json and trying to create dynamic elements but the problem is I am not getting any console errors and not seeing json on UI.

I didnt find any example related to Polymer2.0 for iron ajax and finding only polymer1.0 iron ajax examples

polymer-input.html

The JSON above is invalid - try adding double quotes to the top level keys.

is properties.json even valid? should not the first { be [ for an array?
