The answer to this is changing the tuple type that contained the 2 string types to a row containing the 2 string types instead.
So for the provided schema, the incoming data structure was
Row(string, Array(Tuple(String, String)))
This was changed to
Row(string, Array(Row(String, String)))
in order to continue using the same schema.
