yeah, it's only when trying it a hdt datasource (which is the recommended datasource):

{
  "@context": "https://linkedsoftwaredependencies.org/bundles/npm/@ldf/server/^3.0.0/components/context.jsonld",
  "@id": "urn:ldf-server:my",
  "import": "preset-qpf:config-defaults.json",

  "title": "My Linked Data Fragments server",

  "datasources": [
    {
      "@id": "urn:ldf-server:mySparqlDatasource",
      "@type": "SparqlDatasource",
      "datasourceTitle": "DBpedia (Virtuoso)",
      "description": "DBpedia with a Virtuoso back-end",
      "datasourcePath": "dbpedia-sparql",
      "sparqlEndpoint": "https://dbpedia.org/sparql"
    },
    {
      "@id": "urn:ldf-server:myHdtDatasource",
      "@type": "HdtDatasource",
      "datasourceTitle": "My HDT file",
      "description": "My dataset with a HDT back-end",
      "datasourcePath": "myhdt",
      "file": "somehdt.hdt"
    }
  ],
