Error when using SnarlTemplate with Stardog 7

Support Bug
1

Hi,

After migrating to Stardog v7 (7.2.0), I am getting the following error when calling snarlTemplate.ask("ask query") in one of java projects:

  com.stardog.stark.query.QueryExecutionFailure: com.complexible.stardog.plan.eval.ExecutionException: class **com.complexible.stardog.plan.optimizer.EmptyNodeOptimize does not exist, cannot insert an optimizer before it**

Could you please help resolving this issue?!
On the forum I saw someone faced a similar problem. Although the Stardog.core dependency is already included to the project, I still get the error.

Note that the other ticket mentions the "cache-core" is the missing dependency.

Hi @jess. I installed both the packages. No effect, still get the same error.
