Description

When the exception is an invocation exception during function lookup, we return a useless/confusing error message:

For example,

      df.selectExpr("format_string()")

or

      df.selectExpr("concat_ws()")

Below is the error message we got:

null; line 1 pos 0
org.apache.spark.sql.AnalysisException: null; line 1 pos 0
