'Unbox not working while running AWS Glue on local container
I'm running AWS Glue jobs on my local machine, for study purpouses. For do that, I've follow this tutorial. I've already create a spark Dataframe, and converted it to a glue DynamicFrame using DynamicFrame.fromDF(). I've printed a schema and showed 2 lines of each, and it worked. But when I apply an Unbox method (to convert a JSON string column to a Struct column type) the dataframe returns an empty dataframe, but doesn't return any error. When I run printSchema on the unboxed dataframe, it only returns the root. Can it be an docker image error?
I'm following this tutorial of Unbox class.
