Describe the bug

%%graph_notebook_config
{
  "host": "localhost",
  "port": 3030,
  "ssl": false,
  "sparql": {
    "path": "ds/sparql"
  }
}

This config found in graph-notebook/tree/main/additional-databases/fuseki didn't run the queries successfully, the only config that succeeded was path: "ds" not "ds/sparql"

• OS: [Dockerfile]
• Browser: [Google Chrome]
• Graph Notebook Version: [3.7.3]
• Apache Jena Fuseki Version: 5.1.0

• To Reproduce Steps to reproduce the behavior:

  1. Create a new cell
  2. write

     %%sparql --expand-all
     SELECT ?s ?p ?o
     WHERE { ?s ?p ?o }

  3. Run
  4. Throws an error {'error': AttributeError("'DataFrame' object has no attribute 'map'")}

Hi @ibrahimfathy2 , thank you for submitting an issue!

This config found in graph-notebook/tree/main/additional-databases/fuseki didn't run the queries successfully, the only config that succeeded was path: "ds" not "ds/sparql"

I tried out both [dataset] and [dataset]/sparql paths on Fuseki 5.1.0 + graph-notebook 4.6.0. It looks like Fuseki allows the extra /sparql path for read queries, but not update queries. Both read and write work fine in the base [dataset] path.

Not sure if something changed Fuseki side paths since that documentation was contributed, but your suggestion looks valid. I'll add an update to the current docs, thanks!

Regarding:

Graph Notebook Version: [3.7.3]

%%sparql --expand-all SELECT ?s ?p ?o WHERE { ?s ?p ?o }

Throws an error {'error': AttributeError("'DataFrame' object has no attribute 'map'")}

To match, I tried downgrading my graph-notebook version from 4.6.0 to 3.7.3. This also broke my ability to use %%sparql against Fuseki 5.1.0.

Graph-notebook v3.7.3 is over 2.5 years old at this point, and may not have the best compatibility with the latest graph database versions. Can you try upgrading to graph-notebook v4.6.0 and see if that resolves the issue?
