I have a Virtuoso server running on a remote machine and can access the conductor UI by logging in as dba user. I have created a graph using Linked Data → Quad Store Upload on which I am able to run select SPARQL queries from Linked Data → SPARQL. However, when I run INSERT DATA query I am facing the following error.
Virtuoso RDF02 Error SR619: SPARUL INSERT access denied: database user 108 (SPARQL) has no write permission on graph http://localhost:8890/dummy
I have checked on System Admin → User Accounts that the users SPARQL/dba have SPARQL_UPDATE, SPARQL_SELECT role. I have checked Linked Data → Graphs → Roles Security and it seems fine. I have the same setup on my local machine on which I initially faced a similar permission issue but after granting roles SPARQL_UPDATE, SPARQL_SELECT role it was resolved.
Please suggest how can I avoid this error.
