Hi @Nathant93 ,
Does it come with a "Caused by" in the error stacktrace? If there isn't any in the Spark logs, perhaps you can provide a reproducer code leading to this exception. Stacktrace, DBR version and repro code would help.
The (java.util.concurrent.ExecutionException) Boxed Error, itself, is just a top-level error, so it could be many things.
