Error fetching catalogs

[lukavdplas]

Currently, if I start up a local server from the develop branch, catalogues won't load. Console shows the following message:

Uncaught Response has no @graph key, is this JSON-LD in compacted form?

@tijmenbaarda I see you wrote the JsonLdCollection that throws this exception; any idea what's going wrong here?

[tijmenbaarda]

I don't get this error on the latest develop branch. Could you show the contents of the response?

Ah, I see, the context is missing. That is likely because a version of restframework-rdf is installed that does not have the JSON-LD context support yet. The version of restframework-rdf in requirements should be pointing at the git version, but I will make a release later today, because pointing at git branches in requirements.txt does not always work well.

[lukavdplas]

Yes, I had run pip install -r requirements.txt but that may be the problem. Thanks!
