I was trying to use the code meta generation instance at https://servicemeta.apps.tc.humanbrainproject.eu/

But I encountered the following issue:

Unknown field "schema:affiliation" in "author".

At the moment, the generated codemeta looks like the following:

{
    "@context": "https://gitlab.ebrains.eu/lauramble/servicemeta/-/raw/main/data/contexts/servicemeta.jsonld",
    "type": "WebApplication",
    "alternateName": "Siibra Explorer",

                "name": ""
            },
            "email": "xgui3783@gmail.com",
            "familyName": "Gui",
