> In `ExpressionEncoder.toRow` and `fromRow`, we will catch the exception and put the treeString of serializer/deserializer expressions in the error message. However, encoder can be very complex and the serializer/deserializer expressions can be very large trees and blow up the log files(e.g. generate over 500mb logs for this single error message.)
> We should simplify it.
