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.

Sending a Message and Updating it

This example demonstrates how we can use the Send Message Snap to send messages to one or more recipients. To update a message that you have sent to another Slack user/Channel/private group, you need to use the Update Message Snap to pass the timestamp of the original message. The same can be done for multiple messages, at once.

In this example, we use the Send Message Snap to send a message defined as normal text (string) to a user. You can try with sending to a Channel or private group.

Send Message SnapOutput

Message in Slack

Notice that when the Message field is not defined as an expression, the new-line character \n is not rendered as expected. 

We connect a Mapper Snap to capture the timestamp of the message sent. Alternatively, you can feed the timestamp using any other upstream Snap.

Mapper Output

Now, to update the original message, connect an Update Message Snap to the Mapper and pass the New Message text, Channel/User and Timestamp values to it. The Snap replaces the original message with this updated message and shows the following output.

Updated Message in Slack

Notice that we have defined the New Message field as an expression and that it contains the new-line character \n that renders the message with multiple lines, as expected.
