Unfortunately we stopped supporting Spark 2.X.X. It became too much to maintain. If you have the possibility, upgrade to Spark 3.0, 3.1, or 3.2 🙂 That's the newest version we support with release 1.1.0.

We still have 1.0.2 up for Spark 2.X, but then you're on your own.

Although, reading through the error, try adding kotlin-reflect as a dependency to your project. That might solve it temporarily
