Raise an error in the dataflow

HI, I have a lookup that find a specific row. If that row does not exist, I need to create a new one. If it exists, I need to raise an error and trap it with the "on_error" event of the dataflow in order to log it. Is there a way to raise an error and specify the error message from the dataflow? I was thinking using the conditional split and verify if the value returned from the lookup (by set the error config to ignore the error) is not or not. But how can I raise an error when the value is not null?

Thank you,

You'll need a script component in order to do this.

The syntax is:

ComponentMetadata.FireError(...)
