Unbox class

We recommend that you use the DynamicFrame.unbox() method to unbox a field in a DynamicFrame. To view a code example, see Example: Use unbox to unbox a string field into a struct.

  • info – A string associated with errors in the transformation (optional).

  • stageThreshold – The maximum number of errors that can occur in the transformation before it errors out (optional). The default is zero.
