Hi allI hope you are all fine.I have a TDB store contains a small data. When I
query that data directly from JENA, I got results and it works fine. But when I
use Fuseki server (1.0.2) to query the same data with the same SPARQL code, I
got this error:
Error 500: No known block type for 0
The data contains two named graphs and the SPARQL query is:
SELECT * WHERE { GRAPH ?g { ?s ?p ?o}}
I would be very gratefull if any one tell me what is the cause of this error.
Thans in advance

A possible cause is that you used non-transactionally in the past and
didn't flush changes to disk one time, or the app crashed.
The files on disk are in a bad state and you need to reload the data.
Fuseki always updates TDB transactionally if the service is acting
directly on TDB. Direct use from Jena can be transactionally
(begine-commit-end) or non-transactionally.
