assemble.io and gulp some built-in variables are not working

Question

Hi I am trying to switch from grunt-assemble to assemble (in pair with gulp); I am using assemble 0.24.3

My current problem: some of the the built-in variables http://assemble.io/docs/Built-in-Variables.html are not working on both pages and partials, for example:

{{pagename}}

returns nothing, while {{basename}} throws an error:

Message:
    utils.expectedType is not a function
Details:
    helper: [object Object]
    fileName: C:\Progetti\myproject\source\Templates\pages\seminars.html
    files: [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
    view: [object Object]
    domainEmitter: [object Object]
    domain: [object Object]
    domainThrown: false

By the way

<h1>{{basename}}</h1>

has been added to the index.html page file , not to seminars.html (??)

Am I missing something or doing something wrong?

[Edit]

I have to add that I am using handlebars-helpers, too (version 0.10.0)

Answer 1

I found an answer by myself: just use:

{{basename path}}
