Sample script to include a warning message in a user event script.

To add a warning message to a user event script, you can use the N/ui/message module in SuiteScript which provides a way to create different types of messages (e.g., warning, confirmation, error) and display them on the form. Below is an example code snippet showing how to create a warning message within a user event script.

displaySuccessMessage{
        try {
          let form=scriptContext.form
          let confirMessage = message.create({
            title: "TITLE",
            message: "MESSAGE",
            type: message.Type.CONFIRMATION
          });
           // Add the message to the form as a field
          form.addPageInitMessage({
            message: confirMessage
          });
        }
        catch (e) {
          log.error("Error @ displaySuccessMessage", e);
        }
      }
