Error AgnosticEncoder.isStruct() in Intellij using Scala locally.

I've been trying to execute a connect to Azure Databricks from Intellij using Scala locally, but I've got this error below:

This error happened when is tried to run a show() command for example, but a simple printSchema() works. I have no idea why this happen.

Cluster DB Info:

Any idea?

Hi @Retired_mod,

I ensured that I was using the correct Spark version that matched the version of my databricks runtime, which was the same. But I tried use the Spark version 3.5.1 locally in the .sbt dependencies, then this worked, kind strange.

Anyway thank you very much @Retired_mod, your comment was very helpfully.
