Error: Value Does Not Fall Within The Expected Range. Error In Buffer.DirectRow Method

Hi

I am trying to make a custom task. The custom task has one input, which i map to externalmetadata column in the task and one output.

When i run the task it fails with this error ( I am putting the whole SSIS message)

SSIS package "Package.dtsx" starting.

----------------------------



This is my piece of code which is trying to put the data in the output buffer (ProcessInput function).

int GoodOutputId = -1;

IDTSInput90 inp = ComponentMetaData.InputCollection.GetObjectByID(inputID);

//GetErrorOutputInfo(ref errorOutputID, ref errorOutputIndex);

GoodOutputId = ComponentMetaData.OutputCollection[0].ID;
System.Console.Write("Here i am");
System.Console.Write(GoodOutputId);
if (!buffer.EndOfRowset)
{
while (buffer.NextRow())
{
if (_inputColumnInfos.Length == 0)
{
buffer.DirectRow(GoodOutputId);
}
else
{
buffer.DirectRow(GoodOutputId);
}
}
}

I have put any code in the else part as i am just trying to run the task as of now and later put the functionality in it.

Please let me know if i have missed something. Thanks in advance.
