Could not parse JSONLD

[elf-pavlik]

This example scenario should be enough to reproduce:

  Scenario: Test JSON-LD
    * def oidcContext = 'https://www.w3.org/ns/solid/oidc-context.jsonld'
    Given url oidcContext
    And header Accept = 'application/ld+json'
    When method GET
    Then status 200
    * print response
    * def dataset = parse(response, 'application/ld+json', oidcContext)

It errors with

>>> failed features:
js failed:
>>>>
01: parse(response, 'application/ld+json', oidcContext)
<<<<

In my test I wanted to parse a Client ID document, but it seems enough to try parsing Solid-OIDC context and it fails.

It could be related to JSON-LD 1.1
When I try to parse https://www.w3.org/ns/activitystreamsit works fine
