'Unknown datatype: JSON.' in ADO.NET Provider for Presto

I’m getting the following exception when trying to run the following code.  Does the driver support the Trino JSON type?  I don’t see json referenced in GetResultTypeData method source.

string sql = "SELECT _id, CAST(extra_columns AS JSON) as extra_columns FROM hive.default.measures";

PrestoCommand cmd = new PrestoCommand(sql, connection);

PrestoDataReader rdr = cmd.ExecuteReader();

  Message: 
Test method Juniper.Test.Trino.TrinoClientTests.PrestoAdoRead threw exception: 
System.Data.CData.Presto.PrestoException: [500] Could not execute the specified command: Unknown datatype: JSON. ---> oro230j.TC: Unknown datatype: JSON.
