Description:

I have developed an ASP.NET Core Web API utilizing Gremlinq for CosmosDB graph data access. The service, injected with IGremlinQuerySource, is registered as a singleton.

The issue arises after the service has been inactive for a few hours. Subsequently, the first Gremlin query results in a System.ObjectDisposedException associated with the semaphore.

Error log:

[2024/02/22 22:51:42.583  DBG]  ThreadId :74 ExRam.Gremlinq.Core.AspNet.GremlinqQueries Executing Gremlin query 2d455629-6d93-4720-89c5-9bb3c6f7d5c9 (Script=g.V(_a).hasLabel(_b).limit(_c), Bindings={}).

System.ObjectDisposedException: The semaphore has been disposed.

Any idea what could be going wrong? It occurs for every Gremlin query and not for a specific one.
