Tested:

curl -X POST "https://dev.moss.dbpedia.org/api/save?repo=databus.dbpedia.org&path=kurzum/provider.example.com/dataset1/2018.03.11/test.jsonld" -H "Content-Type: application/ld+json" -d '{
    "@context" : "https://raw.githubusercontent.com/dbpedia/databus-moss/dev/devenv/context2.jsonld",
    "@id" : "https://databus.dbpedia.org/kurzum/provider.example.com/dataset1/2018.03.11",
    "isExtendedBy" :  {
        "@id" : "#layer",
        "@type" : "DatabusMetadataLayer",
        "layerName": "simple",
        "created" : "2024-03-01 14:37:32"
    },
     "subject" : [ "oeo:OEO_00020033" ]
}' -i

with a layer mismatch test.jsonld vs simple and it went through

I also submitted invalid JSON accidently and received a 500

It's natural that these are not done yet, I submitted them, because they could be good test cases for development.
