iron-ajax can not find generateRequest()-Method

Question

I am new to Polymer and try to create an ajax call by iron-ajax. I run into an error, that generateRequest()is undefined.

Polymer 1 is in use.

I installed iron-ajax with this command: bower install --save PolymerLabs/promise-polyfill#1

And as you can see, I load it with <link rel="import" href="../bower_components/promise-polyfill/promise-polyfill-lite.html">

I compare it with some examples but can not find the mistake. Does someone has an idea or solution?

this is the code:

You need to install iron-ajax:

bower install --save PolymerElements/iron-ajax

Then, you can import using the following code:

<link rel="import" href="../bower_components/iron-ajax/iron-ajax.html">

Your code will work after you do the above things.
