Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter while running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

• Stop Pipeline Execution: Stops the current pipeline execution when the Snap encounters an error.

• Discard Error Data and Continue: Ignores the error, discards that record, and continues with the rest of the records.

• Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.
