grundprinzip opened a new pull request, #38879: URL: https://github.com/apache/spark/pull/38879
### What changes were proposed in this pull request? Previously, when passing wrong argument types to the DataFrame methods it would silently try to call methods on the argument types expecting valid input types. This would then fail with illegible stack traces that don't help the user. This patch adds better type assertions and error messages for cases where lists of Columns etc are expected. ### Why are the changes needed?
