How to use Parameter List of integers for Oracle with Dapper?

I am trying to re-write some code to use Dapper so I can easily use parameters. I am trying to execute an UPDATE statement on an Oracle database. A list of IDs to UPDATE is passed in as List<int> as parameter. I want to update a field for each of the IDs passed in. The following is what I have:

OracleConnection connection = ... // set earlier

public int IncreaseProcessCount(List<int> ids)
{
    var rowsAffected = connection.Execute(@"UPDATE TABLE SET PROCESSED_COUNT = PROCESSED_COUNT + 1 WHERE ID IN @ids", new { ids });
    return rowsAffected;
}

Before using Dapper, the execution statement was working just fine. Now I am getting following error:

ORA-00936: missing expression.

My current solution is based on below posts:
