del() cannot accept strings, but put() can

[BigBlueHat]

var jld = {"@context": "https://schema.org/", "name": "BigBlueHat"};
db.jsonld.put(jld, console.log.bind(console));
db.jsonld.put(JSON.stringify(jld), console.log.bind(console));
// have the same result
db.jsonld.del(jld, console.log.bind(console)); // works
db.jsonld.del(JSON.stringify(jld), console.log.bind(console)); // doesn't...
//results in...

Apparently jsonld.js thinks any string is a URL, so input will need JSON.parse()'ing first.

Good catch! Fix coming.

Actually I can't reproduce the error. Neither with your jld var and the different one in the url key of the error. (Trying this in the console of the playground)

Ah, just reproduced it finally. It fails with:

db.jsonld.del(JSON.stringify(jld), {preserve:true}, console.log.bind(console));
