I am testing a LF Cloud Rule that runs a C# script via the Agent. I get this message and I am not sure what this means

This is my test script

namespace ClassLibrary1
{
    public class Class1
    {       //This is a method that takes inputs and returns outputs
            //The names of the input and output parameters configured in the Rule are used as input and output Dictionary keys
        public static Task<IDictionary<string, object>> MyScript(IDictionary<string, object> inputsFromRule)
        {



            var outputsFromScript = new Dictionary<string, object>();

            outputsFromScript["Status"] = "Finished";

            
            try
            {


OdbcCommand command = new OdbcCommand(inputsFromRule["Query"].ToString());
                using (OdbcConnection connection = new OdbcConnection("Driver={ODBC Driver 11 for SQL Server};Server=(local);Database=WorkflowData;UID=X;PWD=X;"))
                {
                    command.Connection = connection;
                    connection.Open();
                    command.ExecuteNonQuery();

                    // The connection is automatically closed at
                    // the end of the Using block.
                }
            }
            catch(InvalidCastException e) { outputsFromScript["Status"] = e.Message; }

           

            return Task.FromResult<IDictionary<string, object>>(outputsFromScript);

        }
    }
}

Update:

Trying to use a different library and getting another error I am not sure what to make of. The odd thing is that I should never get any errors back from the agent. I am using a try catch to ensure the error is sent back in the status in case there is anything wrong with my code:
