It seems that the linter sends quite a lot various acceptable media types in the Accept HTTP header, but unfortunately, when receiving non-HTML based content (i.e. application/n-triples) it fails to provide any results and claims an error occured.
Is there any chance of having that corrected? I believe two solutions are available: remove unnecessery media types and leav only those that are actually supported (quick) or present parsers for other media types.
