See original GitHub issue

Hello, I am trying to explore on DataFrameInputExample using “org.opencypher.morpheus.examples.DataFrameInputExample” and I am running into an issue at below step. I was using “morpheus-spark-cypher” jar file extract in my spark session

val result = graph.cypher("MATCH (n:Person) RETURN n.name")

Appreciate if i can get some help to resolve this and move forward. Error message is below.

Hello @Mats-SX

Issue got fixed. Looks like this issue is with Spark version 3.0, It works fine with spark 2.4.2. Probably it needs rebuild with some additional libraries. Appreciate your response.
