This was caused the the additional check added in PR #906

@JPEWdev - Did you intend for the additional checks to be added in PR #906? Perhaps we can just revert those changes?

The failure is caused by sorta-malformed JSON in docs/annexes/including-security-information-in-SPDX.md. I say "sorta" because the JSON snippets in that file are not portions of a single JSON document with intervening explanation, but multiple more-or-less complete standalone JSON documents. This results in a file which does not even parse as proper JSON, much less an RDF graph. The error message points at the line immediately after the first JSON snippet from the file ends, where the second snippet starts.

I recommend that we not look for documents to parse with grep, and instead list them specifically. I will post a PR to this effect shortly.
